Which is another reason to get the Hilary Page Guide to Watercolor Paints
book. She has pix of each watercolor paint (1400) and you can compare their
relative strengths by looking at the water wash square next to her rating.
D Smith is much more intense.
And I wanted to answer Joe S's letter about gum arabic and watercolor,
below: after I said my message below I realized I should have clarified
what I meant. One doesn't generally use gum arabic in watercolor, just as
one doesn't generally use ox gall to help spread the watercolor (kinda like
we
use Tween). Both are tools in painting but not used 100% like gum is in gum
printing. Thanks for clarifying that.

> Hi Chris,
> Regarding the following I believe gum arabic is often used in watercolor
painting to produce exactly the lifting effect you describe. The two common
"mediums" added to watercolors are ox gall liquid which is used to
facilitate dispersal and produce smoother washes, and gum arabic which is
used to allow lifting of pigment. This seems in line with what Demachy is
proposing in his test, i.e., more gum, less stain.
