Idk If You're The Best Person To Come To With This Question, But Are Gold Bloods The Caste That Can Have

idk if you're the best person to come to with this question, but are gold bloods the caste that can have psionics? Or can (for example) indigo bloods have psionics? Thank you in advance!

so first off, while the term psionic tends to be defined much more generally as a fancy term for psychic abilities, the word itself was created for a short story and then later reverse-engineered into a portmanteau of the greek letter "ψ" & "electronic" that briefly took off in the 50s until someone made fun of it and everybody dropped it like a hot potato.*

*some facts removed for the sake of humor

in homestuck proper, the ability resembles colorful lightning. powerful psionics like the captors are shown to be able to lift things, power machinery, & interface with technology. there are four trolls we know were able to use psionics some point or another: sollux, mituna, the psiioniic/helmsman, &... her imperious condescension. information is scarce but vriska talks about this a bit on pg. 7520 while they're trying to strategize.

what we know:

yellowblooded mutants "sometimes" have psionics

HIC is able to use them, too

they're the same color as the helmsman's.

it's very clear from the way vriska talks about psionics here that she is not aware of anyone aside from mutant yellowbloods & HIC who is able to use psionics. (for aradia's and tavros's abilities, blood color seems to be more of a guideline.) what we DON'T know is whether or not other trolls have the capacity to eventually learn to use psionics & other abilities they weren't born with, or if HIC is somehow unique due to her classpect, blood color, or the abilities she recieved as a servant of LE.
