It's www.colourlovers.com, a site that bills itself as a "Color + Design Community for Creative Inspiration."
This is the palette used by Monet:
Looks to me like Always Artichoke, Blush Blossom, Mellow Moss, Night of Navy and Bashful Blue! Or how about the new In Colors Pacific Point or Baja Breeze?
There are thousands of sample color combinations and oodles of resource information for both the color challenged and the color comfortable among us.
As for the use of "colour" versus "color"… that's a subject for another day.
Go check out the various works listed and leave a comment with your favorite "Masters" color combo.
Which masterwork palette would you like to try? Are you a Picasso or a da Vinci wannabe? Perhaps Warhol is more to your taste?
What color combinations inspire you?
Now, are you up to a challenge?
