You have to remember that Sans and Papyrus aren't the only ones to use light blue attacks, there are others such as the guard dog that can only see moving things, all of whom do not have glowing eyes.

Also, you're making a big mistake talking about light blue attacks when that's not even when Sans has his glowing eye in play. Sans glowing eye, which flashes between PATIENCE and JUSTICE, only comes into use when he forces the player into the blue SOUL mode and manipulates the gravity inside the box.

Also, someone who is lazy and spends a lot of time sitting around doing nothing tend to be more patient because they're used to just doing nothing.

On the topic of the comics and fan games, no, those are not real. Disbelief Papyrus and such are all fan made and come from AUs.

The light blue color comes from the SOUL trait of "Patience" and all light blue attacks must have the player be completely still to not take damage. To not take damage, the player has to be patient. This as well goes for the SOUL trait of "Bravery" and all orange attacks must be moved through to not take damage. To not take damage, the player has to be brave and charge head on into the attack.

We do not know why Sans' eye flashes when he uses telekineses. The yellow color obviously has to do with Sans' Judgement in the Genocide Route, trying to give the player the justice they deserve. The light blue color might have something to do with Sans' lazyness causing him to be patient, or might have to do with the fact that when using telekinesis he has to be patient for the player to hit the wall for them to take damage, we don't know.

In any case, the orange eye Papyrus is just an AU version of Papyrus. Papyrus does not even have any orange attacks and it doesn't make sense that he has magic related to orange attacks.
