Radiant eye color change after the third ideal

[KnightSkye Reforged They/Them]

So, we see a bunch of different Radiants' eyes change color after they swear the their third ideal to match the color of the gemstone associated with their order (Kaladin's turn blue, Lift's White, Teft's blue, and Szeth's grey for example) but we never see Shallan's eyes change color from blue to red – like ruby's – after she swears the third ideal. Anyone know why or have theories?

My question has to do with the color of Shallan's eyes currently, because we've noticed over the books that Kaladin's eyes, as he's continued to use his Surge, changed to lighter and lighter blue. Whereas one could argue that Shallan is farther in her Ideals than Kaladin is, yet her eyes have not changed at all.

Right, 'cause they were already light.

Questioner

'Cause they were already light? So it only affects lightness or darkness in the eyes, not necessarily any other color?

It's not like it is-- It's not like it's saying "Light minus 50%".

It's not like Honor is blue and--

No. It is not. It is just kind of the way that the changes the Stormlight is making the body and certain people are already descended from people who had repeated, over time, changes by the body which stopped physically... That's not to say that all lighteyes that's where they came from. There are some that are natural mutations.

It's not just the Spren Bond and oath level (Kaladin's eyes start changing in WoK) - it's also the point the person is starting from. Kaladin's eyes have more to change, so the changes are more noticible earlier. 

Hope that helps
