Question

which statement about color theory is true?
o a. when light enters a prism, it splits into eight colors.
o b. red, green, and blue cannot be formed by mixing other colors.
o c. the color wheel contains the color red-violet, which is not one of the colors of the rainbow.

Explanation:

• Option A: When light enters a prism, it splits into seven colors (red, orange, yellow, green, blue, indigo, violet), not eight. So, this option is false.
• Option B: Red, green, and blue are primary colors in the RGB color model. Primary colors cannot be formed by mixing other colors. This option is true.
• Option C: The colors of the rainbow are red, orange, yellow, green, blue, indigo, violet. The color wheel contains red - violet (a shade that is a combination within the color spectrum concepts related to the rainbow colors in a broader sense of color theory). But the key point is that red, green, and blue as primary colors (in the relevant color model context here) have the non - mixable property.

Answer:

B. Red, green, and blue cannot be formed by mixing other colors.
