I came across Kris's Color Stripes, an amazing blog with an amazing idea - she takes inspirations from things around her and creates color palettes based on them. What an incredible way to hone your color instincts!
This is such a cool idea I want to do it myself. I think it would a great lesson in really looking at what makes color combinations work, and then using those palettes in art, craft, decor or clothing. Either way it would be a great starting point in design, no matter what kind.
This is a set of three palettes she created out of pictures by Iris Velghe, who does some amazing photography, as you can see.

And then I discovered she's a fellow Etsyian (of course!)...so here's some of her own work, available in her shop.
Hope this inspires you to seek out colors that speak to you!
