What color makes burnt umber?

you mix yellow and red to make orange and slowly mix in blue to make brown.. keep adding blue til you reach the desired shade to mimic burnt umber..

if you mix in too much blue, mix in yellow to lighten it, if it turns too yellow, mix in red to bring the brown back…

mixing any type of earth color, it’s just a matter of balancing between all primary.. using this, you can mix ranges from yellow ocher to sepia..

here is both burnt sienna and burnt umber hue that i mix myself.. yes, I’m using watercolor, but I’m sure the same principle applies..

if you have burnt sienna, it’s much easier, you just need to add in ultramarine until you achieve the desired shade to mimic burnt umber, if you mix in too much ultramarine, just mix in burnt sienna to lighten it back up.
