The same amount of red and green make brown. That just makes the simple color brown. If you want a reddish brown use a little bit more red. If you want a darker brown use more green.
If you want a brown that is greenish use the same amount of red, blue, and yellow. Those colors otherwise known as the primary colors.
Hope this helps!
Red, blue and yellow
There are definitely things you can do, but you should just look hard for black food coloring. Combinations like red, green and blue might come close but will probably turn out a disgusting purplish-brown. Your best option depends on what you're trying to color.
Sienna and umber are two common pigments used to make brown colorings. They are often heated or burned in order to darken them. Therefore, "burnt" umber or "burnt" sienna are also brownish pigments.
The only way you can make it gray with food coloring is if the substances you are making the volcano out of is white. You will have to add black food coloring drop by drop until you have the color gray you want. If you can't find black food coloring, mix every color you have together then drip it in. All of the colors mixed together will make black.
White and brown.
the colors that make brown are red and green
Sorry, you can not get brown from mixing two primary colours... you must mix all three to achieve a brown.
Yellow Green and Red make brown dont they?
If you add red to green, you get brown.
good question, they say yellow and brown make caramel but yellow and brown does not make caramel but maybe beige and tan or beige and brown maybe
You can't make brown dyes, the closest to that color is Orange.
It will be the same for just about all colorings, put about a teaspoon of vinegar in a cup ( two wont hurt ) add coloring to your desired shade and then hot ( not boiling ) water, enough to cover an egg.
brown and yellow
