The people voting Baby Blue and stuff are just so used to it that it looks nice, your opinions are skewed to your current likings. If you were starting a game, those wouldn't be nearly as appealing as the HR4 ones Jitspoe made. That's the same reason people have problem's with Jitspoe's wall textures / grass textures. Sorry folks, these bright grass textures or neon grass textures do not look nicer, you could potentially argue they look cleaner but that is really about it.
If you look at it from a fresh view, entering a game, the normal HR4 texture is nicer, but everyone will argue this saying they the bright textures are so much nicer. I honestly think DP should just stop trying to look 'real' and go toon. The physics are already unrealistic, why not make the game toony.
Also -- If those light barrels don't become bannable (I know people get warned etc..) then it needs to be publicly posted or something, so everyone knows. Because yes, they are a slight advantage over the normal ones. You can clearly see player models beside those, unlike the normal ones at times.
