I've been getting some emails about where the color mixing formula page went (and had to hunt it down myself!). While we're restructuring some things on the two websites it will be tough to find. Here it is for anyone who might need it:

What about the easel?
I thought I heard Mark is working on another design?
Can that page be restored as well?
Thank you!
Pthalo is one of the power pigments not possible to mix. Buy a tube or wait for the Geneva product.

Waiting for easel design..
Yes.

Winsor Blue was created in the mid 1930s, and was launched by Winsor & Newton in 1938 (Winsor Green followed a few years later). It comes from the phthalocyanine family of colours which were first chemically synthesized in the late 1920s. Many new synthetic organic pigments were being discovered around this time, however only three were universally accepted for their artist quality in the 1950s: Phthalocyanine Blue, Phthalocyanine Green and Alizarin Crimson.
Winsor Blue was created to replace the capricious, less reliable Prussian Blue. It has many of the same properties including its intense richness of pigment and therefore great tinting abilities. It mixes very well with other colours (though one must be careful not to let it overpower) and when thinned, can be used for glazing with great effect. It is stable, intense and insolvable except in sulphuric acids. A reliable colour, Winsor Blue or Phthalo Blue is present in most colour ranges and is a great asset to any painter.

Assume the name 'Winsor' is a WN brand name for the color. The WN tube says PB15, PY3. Would this be a greenish or reddish phthalo blue?
When color mixing the results were virtually identical (small differences in the greens and purples that could be just my imprecise mixing).
My Phthalo Blue is a local brand (PB15.3 only). It may be a color where it pays to buy a quality brand.
Pigment Yellow 3 (PY3) suggests a greenish phthalocyanine blue.

FUB is distinct by being synthetic in its chemical composition and is toward the violet range.
