This is something that has been bugging me for so long, and I have written about it before. I also remember sending the big cheeses a PM about it, but I guess it went unnoticed.
I have currently two flashes (DIY TV Repair and Round Flash) that need the background color to be a constant for the illusion of modifying the flash stage. I have 3 flashes under works that would need it too, but I refuse to work on them, because there will always be a large percentage of people who will not see it correctly, just based on which link they click to do virtually the same thing.
Can I ask people to use the pop-up? No, that's stupid, and I don't want to feed people my habits. I'm always for choice and option, and limiting them for a cheap trick is not good.
Can I write a script to tell, which one (pop-up or float) is the user using, and reassign the color in the flash that way? No, it's firstly way beyond my capabilities and secondly not a good thing at all. Also, since I do still keep up a hope that this will change in the future, it would be a waste of my time. Furthermore, both of the flashes use black as the bordering color to the effect I want; people using the float with the black background wouldn't see it at all.
As such, I demand that the color is made constant. Preferably the Newgrounds teal (I figure #25272D). It's not that hard: it would take Tom or whoever probably 5 minutes and it won't take that much attention away from your precious ads.
So how about it, Newgrounds?
