Why does HTML think “chucknorris” is a color?

Question

How come certain random strings produce colors when entered as background colors in HTML? For example:

Answer 1

Answer:

• The browser will try to convert chucknorris into a hexadecimal value.
• Since c is the only valid hex character in chucknorris, the value turns into: c00c00000000(0 for all values that were invalid).
• The browser then divides the result into 3 groupds: Red = c00c, Green = 0000, Blue = 0000.
• Since valid hex values for html backgrounds only contain 2 digits for each color type (r, g, b), the last 2 digits are truncated from each group, leaving an rgb value of c00000 which is a brick-reddish toned color.
