I've gathered that most people love bland colors here, didn't know it was juvenile to like loud and bright things ;)
Well, guess I'm just showing my age. I grew up with the first PCs, and historically, the reason to have certain keys in certain colours was to differentiate their functions—whether it was to distinguish the alphanumeric area, make F-keys easier to find, set off tenkey number keys from operands, emphasize special keys like Esc, Shift, Ctrl, Alt, etc. There were
reasons they were certain colours.
Simply using diagonal stripes of bright colours across the whole board seems rather pointless, like cluttering your car's dashboard with a bunch of indicators that don't mean anything. It's pretty and all, but it seems like it'd
obscure what the keys were rather than helping you find 'em.
But then, we're not supposed to look at the keys when we type anyway, so maybe it doesn't matter... But if you don't look at the keys, why bother having all those colours in the first place?
Clearly, there's more going on here than meets the eye. Whatever blows your skirt up, in the long run.
