If i mix a bit of light brown to olive green would that make olive drab ?.only ask couse i forgot to buy some yesterday and need to paint my sherman .as you know its the bank holidays no shops open on easter monday,cheers all .

Try a little olive green and the light brown and a little white. It might do the trick. Try a little on a scrap piece and let it dry to check the color.

Thanks animal

Do it like they used to do in the field. Mix equal parts black and yellow.
