Guild members enjoyed a excellent workshop given by Hamilton Guild Member Vickie Peart.
First Vickie explained about the primary colours and how to mix them into various shades of the secondary and tertiary colours.
The primary colours are Red, Yellow and Blue; these can be mixed to give Orange, Green and Purple.
Starting with a twelve partition pallet we squirted out the three primaries and then, taking care not to contaminate the yellow, proceeded to mix them in varying proportions to give the three secondary and six tertiary colours.
We then painted them onto a colour wheel so as to see the effect after they had dried.
Next we learned how to charge our pens with the colours we had mixed.
The correct way is to charge the pen with a coulour, write a letter or two then, having washed out the brush (or using a clean one) add more paint of a different colour.
In practice one can get away with out washing out the brush each time, unless you are using one of the primaries, especially yellow, which contaminates very easily.
After practicing this technique using the full rainbow spectrum (Red, Orange,
Yellow, Green, Blue, Indigo and Violet) we practiced using a narrower spectrum
e,g, yellow through green or blue through purple.
Sending a bit more time on colour theory we learned about Hue (the quality that distinguishes one colour from another, Chroma ( degree of saturation of a hue) and Value (lightness or darkness of hue).
Tints are obtained when the colour is mixed with White, this reduces the Chroma but increases the Value.
Shades are obtained when a colour is mixed with Black, this reduces both the Chroma and Value.

Rainbow writing, to be effective, should be used sparingly, with just a few words.
A whole paragraph would be too much. Other tools that can be
used to add a little colour into our lives include watercolour pencils and,
my favourite, Rainbow Stix an inexpensive multi-coloured mechanical pencil.
As it says on the box “Write a Rainbow in Every Stroke”.
Vickie demonstrates to Yvonne, Barb, Alice and Joan
In this book Wilcox expands on the colour wheel principle by explaining that true pure primary pigments do not exist and suggests a colour wheel with two of each ‘primary’.
This wheel consists of a purple-blue (French Ultramarine) and
a green-blue(Cerulean), a green-yellow (Lemon Yellow) and an orange-yellow (Cadmium
Yellow) and an orange-red (Cadmium Red) and a blue-red (Alizarin Crimson).
Depending on which you choose a wide variety of subtle colour variations are
possible.
