Black stuff are personel except the arrow that shows where cc2 forums is.
Maybe change the background to black and add some space between the blue C and the edge of that app logo thing.
The logo is great as it is but yeah, it looks bad on my phone.
The logo is already transparent, issue here is because of the forced shape for app icons, it results in that box and there’s not much I can do without making a different icon for the pwa.
