Granulation is one of the characteristics of some pigments that is best seen in watercolour. You may not notice it in oils or acrylics, and certainly not in pastels and pencils. However in watercolour, granulation is a fabulous characteristic to explore. It is also very important since watercolour is basically a 2-dimensional or flat medium, so granulation is a way of adding texture to the wash.
Granulating pigments show their true nature best on damp cold pressed or rough paper though they will tend to granulate to some degree on any paper. For those new to watercolour, it may look as though something is wrong!
Some of the most granulating pigments have been used to create the 25 new mixes from Schmincke - some released in 2020 and some this year. They are available in boxed sets or individual tubes.
The full range of 25 have been made from quite a limited number of granulating pigments. You can see all the colours used to create them in my blog post here - it may be useful to have that open side-by side on your computer screen.
There are five colours in the newest 'Forest' set. The most useful and realistic greens are often created using two or three pigments so these might be useful colours in foliage paintings.
Forest Olive contains Viridian, a PBr7, in this case probably Green Umber, and Yellow Ochre, which is interesting as there isn't a PY43 Yellow Ochre in the Schmincke range.
Forest Green contains Cobalt Green and the brown pigment used in the colour Mahogany Brown (It was also used in the old colour Walnut Brown, which was darker.)
Forest Blue contains Cobalt Green Turquoise (or possibly Cobalt Cerulean) and the Mars Black pigment. Forest Brown contents Cobalt Green Dark, Cobalt Turquoise and Yellow Ochre.
Forest Brown is not as brown as Forest Olive, and contains the stronger tinting Cobalt Green Dark, a PBr7 earth pigment and Yellow Ochre.
Forest Grey contains a brown earth pigment along with Cobalt Turquoise and Mars Black.

There are five colours in the Deep Sea set. Deep Sea Violet is made from French Ultramarine and PBr33, which is used in Mahogany Brown and the Daniel Smith colour Lunar Earth. It is a fantastic pigment that creates gorgeous texture.
Deep Sea Blue is made using Cobalt Green pigment, Manganese Violet and French Ultramarine.
Deep Sea Indigo is made from Viridian and PV62, which I haven't seen as a colour though it makes a lovely granulating violet-blue here. The greens and violet don't show up much in my little dot sample.
Deep Sea Green uses Viridian and French Ultramarine to create this granulating turquoise.
Deep Sea Black uses the incredibly granulating PBk11 (used in Schmincke Mars Black and Daniel Smith Lunar Black amongst others) with Cobalt Blue Deep and Cerulean pigments (used in Cobalt Azure), to create this deep blue-grey with spots of black.

The set of 5 Galaxy colours includes Galaxy Violet, made from Potter's Pink and French Ultramarine, creating a rich granulating red-purple.
Galaxy Pink is made with Manganese Violet and the mahogany brown pigment.
Galaxy Blue is more subtle - like Deep Sea Blue without the violet.
Galaxy Brown has specks of violet in the granulating oxide brown.
Galaxy Black is a mix of French Ultramarine and Mars Black.

The set of 5 Tundra colours have some interesting mixes. Tundra Orange contains Yellow Ochre, Potter's Pink and an earth brown - possibly burnt Sienna this time.
Tundra Pink is a granulating violet made with Ultramarine and Potter's Pink.
Tundra Violet is a dark grey-violet due to the reddish Mars Brown pigment mixed with Ultramarine.
Tundra Blue has a small amount of a brown earth mixed with Ultramarine.
Tundra Green is the Mars Brown mixed with Cobalt Green.

Often, when making colours, manufacturers are producing 'hues' and blending the pigments into new compounds that effectively behave like a single pigment. Mixtures like these are intended to keep the different pigments in the mix separate, so they can each contribute to the liveliness of the colour. What is interesting is that the mixtures in tubes may behave differently from the mixtures of the same pigments then mixed in your palette in your own studio.
I certainly wouldn't suggest this whole range is necessary, but some granulating watercolour mixtures can be really lovely to explore in watercolour painting.
Update - there is also a Volcano set, a Shire set and a Haze set available now. I haven't tried them to show with painted swatches, but you can see them all at Jacksonsart (affiliate link).
