What happens if we mix blue and red litmus solution together?
Answers
You are probably thinking that the answer to this question is purple or violet, and that is true but it is only part of the answer. Combining red and blue together makes purple if you are talking about pigments, certain types of materials which can be combined together. However, if the discussion is centered around the visible light spectrum, then combining red and blue together creates the color magenta.
As far as the light spectrum goes, blue and red are primary colors on the spectrum. This means that the red and blue are manifestations of electromagnetic radiation visible to the human eye, and they can’t be created by combining different colors together. This is the reason that digital paint programs use values given in the RGB (or red, green, blue) format.
