Accepted Colors: Only the following colors are recognized: black, white, grey, pink, red, orange, yellow, green, blue, light blue, purple, brown. Any other shades will be categorized under the closest matching color on this list.
Shades Don't Count Separately: Different shades of the same color (e.g., dark red or pale yellow) do not count as separate colors. They will all be classified under the primary color (e.g., "red" or "yellow").
Exception for Blue: If a flag contains only one blue, it will be classified as "blue." If there are two blues, and one is significantly lighter, the colors will be classified as "blue" and "light blue."
Counting Colors: The total number of colors on the flag will only reflect these accepted colors, with no distinction made for minor shade variations (except for the exception mentioned with blue).
