Normally I would adhere to the "to each his/her own" centiment,but as I see it,studio monitors are meant to be neutral-such as black,gray or some sort of metal color,so that they will blend into any studio you put them in.
I think colors are fine though,as I've seen some pretty magnificent color schemes,but I think each brand or company,should offer an assortment to choose from,just like you would get from a hi-fi home entertainment system.
Sound & performance are paramount,so I don't think a person should have to be tormented by thier decisions to choose a monitor,partially based on appearance,because afterall,these are monitors you have to live with everyday.
I know that companies have to adhere to some sort of profit margin,but the demographic that some of these companies are aiming for,are some individuals who want to be flashy & trendy-to make some sort of statement,but studio monitors were meant to be a mixing tool,not a frichen surfboard!!
Let's face it,KRK is designed in California & despite thier monitors being manufactured in China-there still very expensive compared to the competition...people out there have issues with designs!
My KRK's were reasonably priced,only because a new line came out,& these old ones were reduced to move out the door.
