Colour & tone

I went to an artists group meeting yesterday evening where someone was talking about her art (silk-screen printing using old maps and letters) they were pretty, but not entirely to my taste.   I liked the idea of them, but visually they were a bit too... similar, I suppose.  But perhaps I should have seen them in the reality : she had brought a slideshow, but it's not the same.

Anyway, after that bit, we did a painting exercise looking at colour and tone : the idea being that when you are looking at colours, it can be hard to work out if the tone is a pale one or a dark one. She gave us a black and white card, and we had to paint the tones in it using colours, with the aid of a phone, which we used to change the colours to black and white so we could see the tones and not the colours we were painting with.
