ITPEC IP October 2020 Question 25
ITPEC IP October 2020 — Question 25 of 100
Equal full-intensity red, green, and blue light combine to form white in additive color mixing. Displays emit these RGB primary colors; adding their light increases brightness, and all three together stimulate the eye as white.
Answer (c)
Why not others:
- red plus blue produces magenta or red-violet
- red plus green produces yellow
- green rust is not a result of RGB additive mixing
Key rule: Additive RGB mixing starts from black and adds light: red + green = yellow, green + blue = cyan, blue + red = magenta, and all three = white.
