New Lessons in Colour

I've been reading Sidewalk Art by Julie Kirk-Purcell.  It's about using pastels to draw on the pavement and the art form that it has become.

I learned some new things about colour that could be applied to dyeing and quilting.

1. Mixing the primary colours together produces a warm to cool dark grey.
2. Analogous colours (next to each other) have similar levels of light waves
3. Complementary colours (opposite each other) have light waves that are mathematically opposite to each other.  That is why they 'show each other off'.
4. Mixing complementary colours together, results in grays or browns as the opposing light rays cancel each other out.
5. Mixing colours lowers the intensity level of the original colour.
6. When you add white (tint), or black (shade) to a colour, you cause it to shift a little into the cool spectrum - green or blue.  This changes the temperature of a colour.
7. If you mix in gray to a colour, you create a tone which doesn't change the temperature.
8. The less intense a colour, the further in on the colour wheel it is.

That's a lot to have learned and recognise from 4 pages.

I'd recommend this book - the artwork is simply beautiful.  Thank you Julie!
