My great respect to watercolour masters. I find the medium harder to control and more fickle. already I find acrylic drying abit too fast ..guess I have to work up the Muse at a faster beat.

Using an allover wash/underpainting on canvas is de rigeur ..for many reasons, including less intimidation by a blank white canvass.

So does, the yellow orche have a tiny bit of brown..to create more brown/light golden skin tones with mixing cadimium red light?

The yellow that was taught to us is a light lemon yellow, which is more a cold yellow (on the colour wheel). Yellow orche sounds like a diminished yellow...meaning it must have abit of dixodine (sp?) violet for orchre cast.

cad. red light - yellow ochre - white
or
cad red light - naples yellow & white
