Hello,

I believe the Challenge is complaining about your first gradient starting with the color "TARDIS". I believe that you can remove your first gradient which should remove the source of this error. The reference in Task 1 about "TARDIS" blue was likely in reference to the hex code #102372 in Task 2.

yeah, that question was unnecessarily confusing, TARDIS isn't a color lol

Thank you. The challenge said it was a second gradient so I left the first one there. The first challenge did not complain about "TARDIS". Oh well.

Thanks, Dan

Hex colors only have 6 values. Your first endColor "#ffffffff" has 8, thus is an invalid hex.

Actually, 8 values is a valid value since it would be #AARRGGBB where AA is the alpha value.
