I understand that it is probably too late to answer) But I have something to say
Don't be surprised that I am answering completely opposite answers with one message))) Because you are both partly right. What am I talking about?
Metal can indeed simply reflect the sun's rays without even heating up, but this is only on the condition of perfectly polished metal, which will look like a mirror, in our case (looking at the photo) Colossus has a VERY weak reflectivity, because barely noticeable reflections are visible on it, its reflectivity should be around 30%, which is essentially matte.
So in any case, it will absorb a lot of heat because of this, and due to the high thermal conductivity of metal, this will happen extremely quickly.
Regarding temperatures and "burning", I would say that in the comics it is shown "approximately" to reality, why do I think so? If someone really wants (and I don't), you can find a video where a frying pan heated up from high heat and then an egg was broken into it and the white coagulated literally in seconds, which means that the scorching sun was able to heat the pan to about 120+ degrees Celsius, so the Colossus could well have heated up to 150 and higher, because in the desert the reflectivity is even greater and it is on all sides, also the Colossus is larger, which means the heating can be even higher, so I think everyone understands that if you press your hand to this for a couple of seconds, you will get a steak))) But more attentive ones could say: If everything is correct, then why did you say that it is "approximately?"
Although the temperature of the Colossus is capable of frying a steak, this does not mean that it could burn a glove or almost burn a hand not even from holding it but from patting it, this is complete nonsense.
Firstly, it's not some 2 thousand degrees, the glove won't burn in a couple of seconds even if you throw it at the Colossus, especially if it's a leather glove, it won't even start to burn, it will just start to dry out and then just char, even a thin layer will give you the opportunity to withstand a couple of seconds at such a temperature without pain, and maybe more, because the heat transfer through it is not that high, and in our case it was a pat, which reduces contact many times, and in reality it would be possible to pat this Colossus for 10 seconds in leather gloves without any problems without harm to the hand and possibly slight harm to the gloves (( But in reality, after the first or second pat, she most likely felt the heat and would simply remove her hand, nothing would happen to her or to the glove in that case, so nothing serious, at least until you want to hug him with bare skin and cuddle for 10 seconds, because then Most likely you will look something like this, and I don't think anyone wants that

So, to sum it up, we can answer it like this.
- The Colossus will heat up because its reflectivity is extremely low.
- The Colossus will not overheat if it is polished to a mirror finish, it will simply be warm.
- The hand will not receive any harm from touching the colossus for a moment even if it heats up to 200 degrees Celsius, the reflex will immediately pull the hand away from the metal and the most you can get is some harmless blister, but after a couple of days of smearing with cream and everything will pass, and if the reflexes are very good, it will do even without this, if you really want, you can find a video of a Russian guy hitting molten metal at around 1500 degrees with his bare hand and he doesn't care about it, the laws of physics baby)))
- In our case, in a glove, even if you do not react immediately, then touching the colossus for a couple of seconds would not cause any harm to the hand and glove, and even more so patting will not even particularly heat the glove, so Rogue most likely would not even immediately understand that it is hot, only a couple of seconds after patting this heat would reach her hand and she would just feel very hot in hand, no more. So the comic is lying.
