More Colour wheels and templates - mixing opposites to create neutrals

Colour wheels take a bit of drawing up, especially as they get more complicated. I use a compass with an ink ruling pen adapter to draw them, and I like to leave a bit of space between each section so the paint doesn't run together.

Here are a couple you may like to choose from to try doing yourself. Each has 18 spaces around the outside. There is no need to have 18 tubes of paint to create these outside colours - it can be done with 8 or less placed carefully at the appropriate place around the circle and then mixed together in different ratios to create the secondary colours in between.

There is a link to the jpeg on my website here so you can download and print it onto watercolour paper and paint is with your own paints.

This one was painted using a small palette of two yellows (Quinacridone Gold and Hansa Yellow Medium), Phthalo Green, Two blues (Phthalo Blue GS and Ultramarine) and three reds (Quinacridone Rose, Pyrrol Crimson and Pyrrol Scarlet. The other reds, oranges, purples, green and turquoise around the outside were all painted with these pigments, then the opposite colours mixed together to create the tertiaries through the middle.

Template for 18 colour wheel with 8 mixed opposites

Here is the template for the wheel above - it has 18 colours around the outside and space to mix 8 tertiaries  through the middle section.

This version is a little simpler as it has less spaces for the opposite mixtures through the middle.

Testing watercolour - creating templates and test cards.

I mentioned I have tested a lot of watercolours.

In one book I have a paint-out of just about every Daniel Smith watercolour, with notes, pigment information, comparisons with other brands, mixing trials and so on. Another book has brief information on every paint I have tried recently arranged by colour. The third, and most useful for sharing comparisons, is a set of cards, one for each colour, that were pictured in a previous blog here. Others books contain test colour mixing...and so on.

I was asked how I set about making these cards so will share it here.

I used Cotman 190gsm paper since it is a little thinner than my usual 300gsm and I was making a large number of cards so I didn't want too much bulk. Note that it is best to test your colours on the paper you are using, or at least all on the same paper to compare results. The paper I used was from an A2 pad, which I ruled into rows all down the page, that is, lots of horizontal lines 4 inches apart. I then used my metal ruler, which happened to be 3cm wide, and a blade, to cut the paper into strips the width of the ruler.

So I had a load of strips 3cm wide with lines down them every 4 inches.

I hope you can picture that.

I then used a stencil to draw the rectangles and squares on them to paint in my watercolour washes. You do have to make sure your method doesn't confuse the front and back of the paper. If you cut them into cards before drawing on them they can flip around easily.

When you are doing a lot of repetitive work you need to find a few short cuts. Sometimes it is worth making my own stencil, sometimes it is worth just repositioning a bought one. I used a Mathomat - a rather wonderful thing I think with all sorts of lovely shapes - to draw the shapes on rather than measuring them up individually. You could of course do free-hand washes. Using the various edges to measure distances between the shapes, I drew on the rectangle at the bottom first, then the square, the the other rectangle above the square, then the two small squares at the bottom.

 

I drew the shapes to be painted in pencil and the other shapes in fine pen and wrote the colour name, manufacturer, pigment information and properties, according to the tube or website information, on the card. I then painted the cards, a wet graduating wash in the top square and a juicy wash in the rectangle. Once dry I cut them up and put a hole in them. 

You could also test how opaque they are by drawing a black line through the shapes with a permanent marker before painting them, or how staining they are by attempting to remove some of the colour once it is dry, but mine are about colour and granulation so I didn't do that.

Any other notes, such as whether the paint didn't re-wet well etc I wrote on the back. My original plan was to put them on a string or in a series of binder rings but at the moment these cards are arranged by colour in a tin for convenience.

Keeping a record of what you have tried is really helpful, what ever method you choose to use.
