Basically yes, look up additive vs subtractive colors… that’s why for a monitor you need RGB, but ink cartrages are Cyan Magenta and Yellow

In short, colored light, and pigments work in opposite ways. Basically all visible light mixes together to make white light. a blue object, basically absorbs the red and green light, allowing only the blue to bounce back… so mixing more colors, means less light. until almost nothing gets out (hence black).
