cinoh:

Colour chart used by Austrian botanical illustrator Ferdinand Bauer (1760-1826) for his field observations. His technique was to sketch a ‘painting-by-numbers’ in situ, which we he could later add colour to after returning from whichever botanical expedition he was on. The example of his painting shown here is a depiction of Grevillea banksii, named for the great Sir Joseph.

You can see a sketch with the numbers here:
