The #colour_collective challenge has been running on Twitter for two years now. It's a lovely community of artists and illustrators and also a brilliant incentive to practice drawing each week. Lovely Penny Neville-Lee started the challenge and continues to post a new colour every Saturday. We then all create a piece inspired by that colour and post our pictures at 19:30 GMT on the following Friday evening.

The first colour of this year was Aureolin Yellow. Here's my contribution : )
