Mixing Colors

I have an old tin paintbox in my sideboard drawer
Now and then I'll take it out from its little store;
Paint pots black and white; yellow, blue and red
Oh, how I enjoy to mix these on my brown palette!

Red and blue make purple
(A shade darker than myrtle);
Yellow mixed with blue makes green
A color very often seen.

Red and yellow turn a fruit
Into an orange lush and good.
Black and white make shades of gray
As with my paint and brush I play.

But here's something stranger still
And the result of God's own will:
If you read His Word you'll know
Red can make black as white as snow.
