I created a color palette of those pearls and beads I liked the most.
Yesterday I discovered one very cool website of Sherwin-Williams internal/external paitings and coatings (http://www.sherwin-williams.com/homeowners/). There is also an additional interactive web application which allows you to upload favorite pics and create color palettes (http://letschipit.com/). Later of course you can find the closest store and order your own color palette for you wall paiting.
So I chipped my color palettes and got very nice color schemes. Enjoy!
After all of course it is possible to turn color palettes to CMYK or RGB or whatever you want!
