The (im)perfect answer

Yesterday I told you that I was  looking forward to some crafty time with my little grandson.  Well, we did have fun, and here’s a bad photograph to show you how we got started

This poor quality snap was taken without him realising, and it would have been impossible to do so later on in the session, so this is all you will get.  The page is about a quarter of the way through, and he painstakingly completed it and then two more.  Such concentration!  He learnt the important difference between firm and gentle too, and I was amazed at how he continued with that during the whole exercise.

So, he now has a new journal – and proof that he can make purple, green and orange.  He was delighted to see them transform before his eyes, and couldn’t wait to pass on the information to his little sister.  She was more interested in his wellington boots, however, but did show some interest when told they were made from blue and yellow!  (Again, apologies for the bad picture)

The comments on yesterday’s post posed an interesting point, and I’ll endeavour to throw some light on it.

Mike10613 said ‘I’m confused now. First I thought how does a television do all the colours when it relies on RGB (red-green-blue) as it’s primary colours. then I thought red and yellow make orange, but your red look pink to me. then I thought. Am I colour blind?’

Yes, television does use RGB, but we weren’t using technology.  We were using pigments, and the primary pigments are red, yellow and blue.  If you think about  the inks printer use (which are used to produce colours on paper and not on a screen) – you will see magenta, cyan and yellow, magenta is a type of red, cyan a type of blue, and yellow – well, that’s yellow!  LOL.  So these are the types of colour we used.  All these pigments can be combined to make the colours of the rainbow and more.  They can be mixed to make the secondary colours, green, blue and purple (that’s by just mixing one with one of the others) or further mixed with both in varying quantities.  Hopefully this helps with the question.  If you need further clarification, just ask.

Incidently, every monitor interprets colour differently, so the colours that you see on the screen may not exactly match the colours we used.
