Or if you want to scan a whole string you could use a very complex regex:

\{[^}]*[^a-fA-F0-9}].*?\}|\{[a-fA-F0-9]{0,5}\}|\{[a-fA-F0-9]{7,}\}|^[^{]*\}|\{[^}]*$

Which will check for any {} with a non-hex character between them, or 0-5 hex characters, or 7+ hex characters, or an unopened brace, or an unclosed brace.
Wouldn't this suffice?

Code:
/^#[0-9A-F]{6}$/i

a) That's not the correct syntax for colour codes.

b) They want to find invalid ones, not valid ones.

c) You forgot lower-case letters.
Explain me how can i use this

\{[^}]*[^a-fA-F0-9}].*?\}|\{[a-fA-F0-9]{0,5}\}|\{[a-fA-F0-9]{7,}\}|^[^{]*\}|\{[^}]*$
