Hi there,
The CSS hex checker is returning false-positive results, for example:
"#3c9c4b is not a valid color 3 or 6 hexadecimals numbers."
"#d4331c is not a valid color 3 or 6 hexadecimals numbers."
"#0d9488 is not a valid color 3 or 6 hexadecimals numbers."
"#f6f6f6 is not a valid color 3 or 6 hexadecimals numbers."
The above are all valid within the A-F 0-9 hex range, and being flagged as invalid.
Not a major issue, but good to fix.
