I don't want to sound like a complete whino, but that brown color of the column
where the number of ppl who solved a challenge are in, looks really ugly against
the blue-greyish background... Just letting you know...

Yea, I thought so too, but it didnt really bother me much, so I wasnt gonna say anything about it.

I agree. The color isn't very apealing.

Now it is again how it was before. If anyone has a good idea for that color, just tell
