On the screen of this laptop, the unsub buttons appear faded to pink, rather than red. (It doesn't have too good screen as far as colours are concerned - my PCs, other laptop, notebook and even cell phone are better for that -, as it tends to lighten things, but there definitely are reds that are far more red ... it just that it makes the pinkness of RPG's "red" especially distinct. The colour picker doesn't have a proper red, either.)
[b][color=ed1c24]This is not red.[/color] [/b] - ed1c24, or RPG's closest colour picker option to red.
[b][color=ff0000]Now this is red.[/color] [/b] - ff0000, or the hex for 255,0,0 in red-green-blue. 
Er... I was just bothered earlier by the fact that the colour picker's red is very I-accidentally-left-it-out-in-the-sunlight-for-a-few-weeks faded pink, but didn't bother to address it. 

Personally, I am not really bothered by the unsub buttons (and I am typically fairly colour-sensitive) - but I definitely [i]would[/i] be by pop-in buttons. The rating buttons popping is already one of the most annoying features on the site... (Can we have these greyed out and permanently visible? [i]Please?[/i])

What slightly does bother me - now, this is a matter with this screen more than others (it is slightly better on other screens, but not good, and this screen simply doesn't go any more darker or more contrast) is the amount of near-white text on fairly light grey background (and in one instance, medium grey on light grey). Tag buttons? Near-white on light grey. Hiders? Near-white on light grey. Reply box? Near-white on light grey. The Unsub buttons mentioned above? White on bleached-red-pink. At least my eyes tell me that either the text should be pure black instead of white or the background should be significantly darker. It doesn't hurt (luckily - I literally am holding a hand in front of the screen to avoid seeing the gloriously neon tags of a certain RPG competitor whenever I go on that site...), nor is it hard to see, but it is a bit tiring combination in abundance, for the lack of better term.
