Colour Theory – Shapes

SHAPES ON CANVAS

DRAW OUTLINES FOR YOUR PAINTINGS

Today we will keep the article very short and simple; not because sketching is an easy job but because going into very deep detail is beyond the scope of this tutorial. For more information about sketching you might want to start reading here:

In any case, applying sketching knowledge to painting will definitely help you and allow you to progress and understand things faster. Very roughly, due to perspective, shapes distort; for realistic paintings you have to draw in perspective rather than regular shapes as you already know them (read here). Also, tones change due to distance; colours look paler as you move further away and more vibrant and “complete” as you come closer. We will cover all these aspects in due course. Regarding the basic shapes for painting, all you need is either a hard pencil (HB, H or 2H) or a thin brush and acrylic paint.

Using a Pencil

In the first case, using a hard pencil will allow you to draw your basic shapes and will prevent leaving very heavy and bold marks (which would definitely happen when using soft pencils 2B, 3B etc or charcoal). Light marks on your canvas can easily be covered with paint. Also, you will avoid mixing your paint with black dust (ie. charcoal) which will make the final result dirtier and darker. Of course you can always apply more than one layers of paint to avoid this problem; it’s entirely up to you. I just find it easier to roughly and lightly sketch the shape using a hard pencil and then paint on top of that. See below:

Light marks on your canvas can easily be covered with paint…

Using brush and paint

In the second case you start shaping your subject directly using paint and brushes. This is very good fun for two reasons. If you use reasonably diluted paint you can always rub it back and clean your canvas. It might leave a mark on your blank canvas but you shouldn’t worry too much as this can easily be covered by the next layer of colour. The second reason is that using a brush and paint you can’t be too precise with your shapes; this way you avoid spending ages detailing something you will then completely cover with paint. I find this technique quite easy, fast, fun and relieves me off the stress of detailed drawing. Of course the amount of detail you want to add is up to you but remember…this is just a trace to help you paint a bit more accurately later.

…avoid spending ages detailing something you will then completely cover with paint.

Few tips when using a brush:

  • Use diluted paint – it’s easier to cover it up later
  • Use light colours – for the same reason
  • Use slightly thicker paint for shapes that are closer to you (gives a sense of perspective – helpful for you); see the blue garlics above.
  • Start simple and experiment – trying a very complicated composition will not help you – most probably will frustrate you.
  • Use less  defined shapes as it is less probable to look wrong (a wobbly building looks very wrong while a wobbly tomato looks like a wobbly tomato…still tasty though!)
  • You might want to use a combination of pencil (for some basic shapes or for perspective lines…) and brush (for rougher shaping afterwards.

Materials

Presumably, you have already experimented with one technique or the other. I would suggest you choose a simple subject (like the bananas and the apple I sketched above) and try shaping the outlines on two separate canvases using both techniques. You will have the chance to compare the two sketches in terms of detail, speed, accuracy and ease. Allow for 0.5 hour.

  • A small brush (a round brush will be helpful),
  • Some diluted acrylic paint (light colours will be covered easier when you block in colour later).
  • Cloth to erase/rub the paint if you need.
  • 2x Canvas (canvas pad – easier and cheaper for this exercise)
  • A hard (2H or H) pencil  (for part of your sketch you might want to try using a soft pencil – 3B or softer to see the difference).
  • Rubber

 

A quick summary of the above is here:

  • Principles of Perspective and Tone.
  • Pencil – More detailed sketch – think if necessary
  • Brush – less detailed but quick and easy

Colour Theory – Complementary colours

COMPLEMENTARY COLOURS

AN EASY WAY TO ADD SHADOWS

Last week we looked at the Colour Wheel which is the foundation of the colour theory. The complementary colours were mentioned in that article, however we didn’t look at those in detail.

20180523_195621When mixing primary colours (red, yellow and blue), the secondary colours occur (orange, green and purple). An easy way to remember which the complementary colours are, is to visualise the colour wheel. Those sitting opposite are called Complementary colours. See below; green is red’s complementary colour, purple is yellow’s and orange is blue’s.

Another easy way to memorise this is that its primary colour’s complementary is the one created by the other two primary colours. ie. red’s complementary is green (blue + yellow). Anyway, lets not make it to complicated. With practice you will be able to remember instantly, until then just open the Colour Wheel and have a look.

The amazing thing with complementary colours is they have the ability to “mute” the primary colours with which they are mixed. This allows you to easily add shadows to your paintings. It is very very useful when you are working with limited palette of colours (ie. red, yellow, blue).

…complementary colours…have the ability to “mute” the primary colours…

Try mixing red with some green. You will instantly notice that the red becomes darker, almost dirty, which gives the impression of shadow. You might want to experiment with the different combinations. I did my exercise recently; see the results below. Later this week we will look at a more comprehensive exercise.

Materials

Again just try to keep it simple.This is not an attempt to create a beautiful painting; we are just trying to explore how complementary colours work.  Allow for 1.0 hour.

  • A small brush (any type will do),
  • Yellow Acrylic Paint
  • Blue Acrylic Paint
  • Red Acrylic Paint
  • Canvas (canvas pad – easier and cheaper for this exercise)
  • A pencil and a rubber

A quick summary of the above is here:

  • See the primary and secondary colours on the Colour Wheel.
  • Those sitting opposite on the colour wheel are called complementary colours.
  • Mix complementary colours to create muted colours which can be used as shadows.

Colour Theory – Basics

COLOUR WHEEL

THE FOUNDATION OF COLOUR THEORY

I recently decided to teach myself the basics of colour theory; I started with the colour wheel. This provides the fundamental background of colour combination and allows you to further develop techniques. In following articles we will explore other aspects of colour mixing and combination.

Materials:

Keep it as simple as possible. The aim is to explore the colours and their combinations, not to make the most beautiful colour wheel ever created.  Allow for 1.5 hours.

  • A small brush (any type will do),
  • Yellow Acrylic Paint
  • Blue Acrylic Paint
  • Red Acrylic Paint
  • Canvas (canvas pad – easier and cheeper for this exercise)
  • A pencil and a rubber

 

…fundamental background of colour combination…allows you to further develop techniques.

The principle of the colour wheel is very simple. You start using the three basic colours; red, yellow and blue. These colours are called the primary colours and are the base and main components of every other colour. Having these three and mixing them in different quantities allows you to mix any other colour. The primary colours wheel is the one right below.

Once you have created the primary colours wheel then, we are ready to start mixing those three together to create our second colour wheel; the wheel of secondary colours. The colours sitting opposite each other in the secondary colour wheel are called complementary colours (this will be useful for creating shadows – see next article). As you might already know mixing the primary colours with each other gives you a first set of very useful colours: Orange, Green and Purple.

  • Blue + Yellow = Green
  • Red + Yellow = Orange
  • Blue + Red = Purple

20180523_192829.jpg

The second step has now been made. We have our secondary colours filling the second wheel. Final step is to create a third colour which will be filled with the tertiary colours. As you can easily guess, mixing the primary colours in different quantities (exactly as you did for the secondary colours above) gives you greens, purples and oranges of different strength. So here you can experiment and create colours you like more by mixing slightly more blue, or a bit more yellow or maybe a bit more red? Create as many mixes you like. For the sake of this exercise I created only a couple of each combination.

A quick summary of the previous steps is here:

  • Primary colours are: Yellow, Blue, Red
  • Secondary colours are: Orange, Green, Purple
  • Tertiary colours are: The combinations of primary colours  using different quantities of each colour. Create Yellowish Green or Blueish Purple etc.
