1. Why are some pigment spots larger (area and volume) than others?


I understand that pigments move up the porous paper by capillary action, from research. But why are some pigment colours (areas) larger? THanks

I'd think the area being larger would mostly imply more of the pigment was placed on the paper. I imagine a very small volume of difference between drops of two pigments would cause a still noticeable difference in the size of the spots.
