I ordered this set (the ten tube Introductory set) along with a handful of other individual tubes to round out my starting collection of gauche. I think this is a great selection for a basic starter set! You could mostly get away with just purchasing the 6 tube Primary set if you’re fairly confident with colour mixing, and in that case I’d strongly recommend picking up an extra tube or two of white as it will go very fast.
The Permanent Green Middle is fairly liquid and separated but it’s workable and a lovely colour, a perfect choice for a primary palette.
The Primary Red is on the cool side, a little pinkish, and has a smooth consistency.
Primary Yellow is also quite cool and somewhat sheer compared to most of the other colours.
Primary Blue is warmer compared to the other two primaries, and is a bit of a lighter and more opaque blue than some others.
Lamp Black is a nice, basic, universal carbon black that washes out into a neutral grey.
Zinc White is extremely thick and opaque, which is handy in a white and also gives it more power when mixing.
The extra tubes in the Introductory set are well chosen to balance the Primaries.
Permanent Yellow Deep makes for a nice warm yellow contrast to the cool Primary Yellow, as does Spectrum Red to Primary Red. Spectrum Red has a lovely vivid bloody undertone to it, a rich edge of rust that makes it a nice natural looking red to have on hand. Ultramarine is an excellent deep, cool contrast to the Primary Blue. Yellow Ochre as a final addition is a bit interesting, but it’s a great colour to have on hand for mixing flesh tones.
A couple notes on the other greens I got:
Linden Green is the most beautiful colour I’ve ever encountered. I’m in love.
The Permanent Green Dark is one of the drier consistencies, interestingly.
Permanent Green Light… The colour is nice, but unfortunately the consistency (at least in the tube I received) is just so binder-heavy and oily that it’s a total nightmare to use. With the 20ish total tubes I’ve bought, there’s a wide range of consistencies, but nothing else even begins to come close to this. I’ve swatched them all and also made up a number of travel palettes with halfpans. Everything else has fully dried, the PGL is still a runny liquid in the pan. Either I’ve got a defective batch or this paint needs to be put in the pear wiggler before use!
