Whenever I read any artist's profile many of them site nature as where they get a lot of their inspiration.
For me a lot of my colour ideas come from what I feel is pleasing the eye, looking through all the beading mags, and websites of gorgeous designs. It amazes me how different designs make colour combinations look either great or not so great. I also love watching what colour choices my customers tend towards when learning to stitch a project. I definitely learn from them as they all choose things I would never have dreamed of using together.
Interestingly someone who blows me away with how she chooses colour is my 8yr old daughter Peita. She is quite a big fan of most things arty and has always sorted and stacked felt pens, blocks, erasers, you name it - and of course my beads. When I first decided to teach her bead stringing a few years ago she actually spent nearly an hour sorting piles of beads into colours, shapes and sizes. I'm not sure how much beading she actually did.
The above is the first time I took a photo of Peita's colour combinations. This was done with Beado's (you know create design and spray with water so they stick together). She created a whole pattern on the template with all of these colours and it looked awesome. This was when she was 6 or 7.
Sorry about photo quality as taken on phone due to broken camera. Here is my beautiful Peita. After making her own necklace with pony beads she decided to sort them all into colour combos.
Some great colour combinations here. Might have to zoom in on this for some inspiration.
