When mixing all colors together, the result can vary based on the color model being used (additive vs. subtractive).
- Additive Mixing (like mixing light colors): If you mix all colors of light (like on a computer screen), you get white.
- Subtractive Mixing (like mixing pigments or paints): If you mix all pigments, you get black or a very dark gray.
Since the question doesn't specify the context, if you need a letter answer for each option:
- gray: A
- white: B
- black: C
- green: D
If you are referring to pigments, the answer would be C (black). If you're referring to light, it would be B (white). Please let me know which context you need!
