How to pick a color palette?

I enjoy trying out new color schemes. There is a site called design seeds that I'm LOVING lately. It's great for color schemes ideas for your home decor and for me, it's awesome to be able to see color next to each other without having to mix it all up first. Check out this little hidden treasure:

So my most recent painting I wanted to go with a Tangerine & Mint color palette. These colors are so complimentary and really BIG right now.

Wild Flowers Series

The past few days in Utah have been uncharacteristically warm and sunny which has brought on an early dose of spring fever. I've been known to get pretty severe cases come mid-February but this year, I'm jumping the gun and ready for the heat say... now-ish. Since I can't really control the weather I've decided paint it. This new series explores my love of the beauty in springtime -- that can't get here soon enough.
