The way they work you can paint one colour onto the surface when dry, choose another colour to go over it and you will see what hue that has become ,you can add the same colour in the next glaze or another colour to change the hue ,you can do this as many times as required until the value has been reached.
I'm sure every Aritst has wondered when coming to the end of a painting what another glaze will look like ,now you can just do that, without the worry of going too dark you can deepen glaze by glaze .Colour choises become easier as you have the luxury of seeing through the colour viewer what it will eventualy look like before you commit giving you a preview.
I have found this a great tool for working with on my paintings
