Yea, that color scheme-- the pastel blue and pink-- has been common in MAP/pedo spaces for a while; the powder pink representing "girl lovers" and the baby blue representing-- you guessed it-- "boy lovers".
The "person" credited with creating/originating the tranny pride flag is a troon by the name of Monica Helms (born Robert Hogge). This particular troon, in addition to checking off all of the standard AGP boxes-- e.g. recounted early memories of erotic cross-dressing with his mother's panties, military service and marriage before coming out in his 40s as a true and honest woman, and leaving his exasperated wife to pursue his fetish 24/7 and cruise gay sex clubs etc. etc. -- he also authored several short stories/amateur smut revolving around forced feminization and-- you won't believe this-- sexualizing children. From the Reduxx article I linked below:
Titled “A Woman Scorned” — published in the collection Tales from a Two-Gendered Mind — a man finds himself being stalked by a young girl who looks “no more than sixteen years-old” and whom he initially mistakes for a Girl Scout.
“The beautiful girl looked at me with her alluring eyes… She announced, ‘All I want is you! I want to marry you,'” wrote Helms.
The child reveals herself to be a witch who claims to be older than she appears; among her powers is the ability to age very slowly, causing her to look “far younger than her true age.” The man marries her and they have a daughter: “Our baby has her mother’s magical powers.”
and:
It is unclear whether Helms was aware of this correlation at the time, but when discussing the symbolism behind the trans flag in an interview in 2017, Helms stated that blue represented young boys and pink represented young girls.
In conclusion: assume all trannies are pedos until proven otherwise.
