The set has all your basic colours to allow you to mix and blend to make any colour you need, plus leather and flesh tones to save you from having to mix those yourself. It would be even better with a second metallic tone, to enable some variation in metallics, but that's a minor complaint.
Not all colours are created equal here, with a few of the lighter colours going on slightly patchy, but every paint brand has one or two colours that are on the weaker side. Overall, the paints are highly pigmented and thin down wonderfully.
The set comes with their “strong tone” wash (a great timesaver), but the paints are high quality enough that you can thin down any colour to create washes of your own.
