I have a bag full of color test swatches and I can't throw them out. The 1st watercolor lessons you learn, is test out your colors on a bit of paper before putting brush to expen$ive watercolor paper.
I get attached to test color scraps.
Sometimes they're better than the finished 'work of art'. After David Dewey's watercolor class I'd go round picking up test scraps off the floor. The colors are lush, splashed on freely. Some of my own color test scraps are far superior to anything else IMO. 
People tear their hair out daily trying to get their walls to look like some swatch of paper with a divine color on it. They fall in love with that color and will settle for nothing else = madness.
In many PB posts I'll mix up and match paint colors to whatever I'm going on about, whether it be macarons, chocolate, swimming pools, cherries, toy birds, ice cream, orange, red, black, pink etc.
I once took a color mixing class at Parsons. We could only use 3 primaries, RED, YELLOW, BLUE. We mixed away till we were blue in the face for 6 weeks.
That's the thing about color. It's so easy to fall in love with. I thought I was mad for RED. All those ridiculous personality tests where they ask you your favorite color, I always put RED. But now I realize it's BLUE I can't get away from or stop using blue all over the place.
Your most favorite/least favorite color etc. The results are not far off:
Hungers for intensity in life and welcomes opportunity to take on challenges and makes a focused effort to solve them. Wants to concentrate energy on achieving goals. Not to be sidetracked by outside influences. Aims to achieve impressive success by expending great effort and single-minded perseverance.
WOW! I'm loving this.
I took Dr. Lusher's color test for this post. You get to choose
A watercolor book I had, Spanish I think, had an exercise for making over 100 colors with just 3. Ilove color mixing and matching. It's a nice meditative exercises.
Tachisme, a French abstract art movement during the 40s and 50s, was a reaction to cubism and the equivalent to American abstract expressionism. Some of Les tashistes were Sam Francis, Hans Hartung, Georges Mathieu, Henri Michaux, Pierre Soulages. Being hooked on blobs, it's a natural that I'd love Sam Francis' paintings. You usually see him surrounded by sheets of paper on the floor -> giant color tests. And he looks incredibly happy. mindless activities you can do endlessly, yet at the same time quite challenging.
It's not as easy to match a color as you'd imagine.
Painting seashells in watercolor.
is a lot like painting blobs.
You lay down a pool of water on your paper.
And then start dropping in the colors, preferably a warm color and a cool color.
You get to play with the positive and negative shapes.
The more blurry the patches, the better.
