Today I thought about perception. I created two beads with dots the other day and I wonder which one appeals to you more. One is completely white. The eye can just see some texture on the surface. Depending on the light the texture seems to change and the white will appear in different hues. (This doesn't really make photography easier...)
The other one was made in my favourite colours, greens and blues.
You will notice instantly that the color adds depth and makes the bead much more interesting. However, the haptic sensation is the same...
