Fresco Colors

I have seen a rather comprehensive list of historical and modern pigments appropriate for true fresco in Kremer Pigments US catalog.

​Hi Koo -I have also had the same frustration over the years. I will share here what i have often shared with others – keeping in mind that this person’s website is….well….Unique? Hard to navigate and find things? A touch crazy? Yes and yes and yes. Plus it reflects only his testing, but I have to admit he has more testing of modern pigments for Buon, Secco and Fresco that I know of or can find elsewhere (Sinopia, Kremer, Natural Pigments). Anyway, Don Jusko’s Fresco testing can be entered from all sorts of places and unfolds in all sorts of ways, but perhaps start here:
http://realcolorwheel.com/fresco.htm
And here are some examples of the types of testing you will find:
http://realcolorwheel.com/frescopigments.htm
http://realcolorwheel.com/fresco3colorchart.htm
http://realcolorwheel.com/fresco13tomatoesredmagenta.htm
Really my only advise on navigating is just to keep clicking through. And again, understand this is one person’s test but it might be better than nothing.

Brian or Kristen might have more solid info but I do have to admit I have a fondness for these types of independent labors of love that you stumble upon.

Hope that helps.

The real color wheel pages are fun and can be useful. Even if they are by one person, they are empirical and not just a regurgitation of what people have read. Thanks Sarah.
FYI I just checked and the downloadable Kremer catalog does have their list of pigment/medium compatibility including true fresco. It is available in PDF below. BTW, you need to go all the way through it to page 93.

Also, we are not familiar with any more substantial resources (especially about non-traditional pigments in lime fresco) other than those mentioned.
