I'm happy to say that I am no longer scared of coming up with beautiful colour palettes! I started out with my tutors way of choosing palettes, because that was the only way I had being taught. I now have a bit of a different way of doing this, although it still incorporates parts of what my tutor told me.
I don't know whether everyone works this way, but I begin with all of my motifs in black and white. I'll work on the composition before I introduce colour into my patterns and illustrations. However once colour is added some of the motifs need to be rejigged to make sure the pattern flows and the colours are equally distributed so your eyes aren't drawn to one particular piece.
On occasion I use websites such as Design Seeds and Colour Lovers which are jam packed full of lovely colour palettes. I prefer to use this method though:
I will pick out quite a few patterns and illustrations where the colour palettes really catch my attention such as these:
Then I'll compile a big palette from all of these colours and make up my own colour palette from these.
My eye for colour is so much better now, and I'll never use a black and white palette in my collection ever again! I love colour too much!
