>>6639559>Just silver with a bit of blueNot that anon, but they actually did nail it pretty well. You might not be able to see the subtle purple due to your phone or monitor settings (or heck, even just your eyesight). I did not modify the colors at all in this image, just changed the levels and saturation so you could see the hues more easily.
Speaking of accuracy though, now that I look at your screencap Robo is actually quite glossy. He's reflecting light quite sharply in the silver portions of his suit. Have we ever gotten a glossy Robo toy? I feel like he's always depicted as a rather dull/flat silver with no reflectivity.
