I like looking at all colors (this goes for flowers, too) and I don't think I could really decide which ones I prefer. Each has its own beauty.
To wear:
Deep blues (indigos, Prussian blues, midnight blue) - extremely calming, put me in a thoughtful mood, make me want to slow down and contemplate
Deep greens (dark emerald greens, dark, rich jade and forest greens) - both calming and warm
Bright scarlet, bright raspberry, other bright red or purplish-red shades, also some darker vinous hues - these are my "happy" colors, they give me an instant jolt of joy when I see them
Any shade of orange, though I prefer the brighter, sunny ones on the border between lighter orange and darker yellow - make me happy too, but in a calmer, more carefree and less intense way
Pastel shades of khaki, gray, brown, beige, lighter green - very soothing, make me feel like I'm blending into the natural environment
