The best match for watercolor is laser dyes, but they must be weatherproof, because watercolor is more exposed to them than the oil technique. They must be light-resistant dyes (all organic ones fall out).
In watercolor less change those dyes that are sensitive in one way or another in oil.
For example:
- yellow chrome - less greening,
- minia - more durable in watercolor,
- cinnabar - does not blacken as strongly as in oil.
Lead white and Neapolitan yellow, which are sensitive to hydrogen sulfide, are impermanent in watercolor.
Zinc white turns color in watercolor in fades.
Kaolin is also used as a white here.
Yellows: aurealine, cadmiums, ochres, mars, natural sienna.
Reds: ugry reds, iron reds, cadmium red, alizarin kraplak (dark).
Browns: dark ochres, mars, burnt sienna, umber.
Blues: ultramarine, ceruleum, Paris azure, cobalt (in splits , because occurring alone it loses color - a physical phenomenon).Greens:chrome green, earth green, cobalt green.
Purples: purple cobalt.
Blacks: ivory, wine.
In watercolor, aqueous iron oxides behave well, as they do not darken (in oil they take more of it and lose their color over time).
Ultramarine is not subject to "ultramarine disease" in watercolor (no weak acids in the binder).
Bright cadmiums and chromiums lose color very quickly here. In this technique, special attention should be paid to the combinations of pigments, as they undergo changes more quickly than in oil.
If the watercolor is to be stored in albums, less light-resistant dyes can be used.
