According to this site, these are the current color codes for a variety of teams:
https://teamcolorcodes.com/
BYU royal: 293
LA Dodgers: 294
Duke: 287
Kentucky: 286
Kansas: 293 (same as BYU)
Golden State Warriors throwback uniforms: 293
Chicago Cubs: 294 (this is the same as the Dodgers, but the Dodgers look like a lighter blue to me)
Just looking at this chart, I'd say "Reflex Blue" is closest to old school BYU royal and 2935 looks more like the current royal uniforms than 293.
