What does red blue make?

Answer 1

green

Somebody was joking here. Usually they make black or a very dark purple.

However, I have seen red and blue produce green. The blue was Prussian blue, which does pass green. And the red was an oil paint version of chromium red, highly diluted to the point where it was yellow orange. Both pigments passed green.

If we are talking red light and blue light, instead of pigments, they make magenta.

Answer 2

Red and blue make purple. You can mix them in different ratios to make warmer and lighter purples. Purple is one of the most difficult colors to mix, so don't get discouraged if it seems weird at first.

Answer 3

Red and blue mixed together make purple. Purple is an ugly color. Mayonnaise is not an instrument.

Answer 4

Mixing red, blue, and orange would make a shade of brown. It would be a very purple brown. It would be the same as mixing 3 parts red, 2 parts blue, and one part yellow.

Answer 5

Together they make purple.
