What design/upgrades would you give to Iron Man's armor?

if you could create a new ironman armor what would its capabilities be and what colour?

Desert Armor: the usual flight and repulsor ray technologies, but with extreme cooling technology so it doesn't let the wearer get uncomfortable fighting in high temperature situtations, ideally venting the excess heat in such a way that the wearer is not readily visible with IR goggles or other heat-sensitive detection. The armor would be tan and pale yellow in place of the usual red and gold color scheme. The paint job would be matte texture, to minimize reflectivity that would make the armor highly visible despite the subdued color scheme. I suppose there would need to improvements in the air intake system, too, or else a highly efficient and self-contained air recycling system, to minimize problems from sandstorms.

Magic armor: Standard Stark armor technology, only with an extra coating of cold iron. And maybe Dr. Strange could slap some enchantments on it to protect the armor from transmutation and the wearer from mind control magicks. Logically, there is no reason why this armor needs to be a different color, but I will arbitrarily declare that it should be light purple and gray in place of the usual red and gold, just so fans like me can go, "Hey! that's the magic armor! Cool!"

Genital armor. So Tony does not have to worry about knocking-up one of his many 1 night stands ;) . It would be flesh colored and ribbed for her pleasure :D .
