Here’s a way to make easy palettes from your favourite photos.
Open Any Photo You Want
Use the Single Row Marquee Tool & Select a Single Pixel Row
Transform (CTRL+T) & Stretch to Full Height
Then Use Filter > Artistic > Dry Brush
So you can just take a photo with good colours and reduce it to a nice palette. I’ve been having lots of fun doing this. Here’s one i made earlier with this pic of my son mucking about..
And this is the palette I took from it by using the eyedropper tool to pick out the ‘key’ colours.
I like it because you get nice natural harmonizing palettes with very little time and effort! You can see more of my palettes on www.colourlovers.com
