I used to think it was "Tangel" castle in Dragon Warrior, not "Tantegel"...
AAAHHH!!!! A Dragon Warrior reference!!! * glomps jdratlif repeatedly * That game owns in a plethora of ways. I still pop it in to the NES every so often to fight some starwyverns and magidrakees. Good times. Very good times. (And, yes, El Guapo... I DO know what a "plethora" is. ) ... As to the topic at hand, I always thought of the power bomb doors as yellow. To my eye, they're about 80% yellow/20% orange, or what you would call "yellow-orange" if you're matching colors using the standard box of 64 Crayola-brand crayons (with the sharpener on the back, of course). I could see, though, that given (a) slightly different color perceptions, and (b) different color settings on different TVs/monitors, that it could appear more orange than yellow.
I suppose they made the doors more orange for people like me, who may find it harder to tell the difference between the doors if the colours are too similar.
I think they should stick a sign on the doors in Prime 3 with an image of the weapon needed to open it, sorta like the blocks in SM. Yeah, I know this should really be in the Prime 3 topic, but I think it fits in better here.

They do this for stop-lights too. The "green" light is actually blue-green for people who are red/green colorblind.
Yellow is fine. It's in the manual, and it's what I used in the program. http://games.technoplaza.net/smse/ if you didn't see my other thread. I can see the yellow in the doors even if they will always be orange to me first. Maybe someday my brain will fix itself and remove the orange association. If not, at least people won't wonder where the "orange" doors are if they use my program.
