I have very little experience with OG so I'm not going to be much help with that part. 3/6 OG in a het x het pairing seems highly unlikely though. They don't have a strong indicator of Enchi in the pattern, but color wise I could see it. I could see them being Mojave with the amount of keyholes and high odds in the pairing, but I doubt that with as golden as the yellows are instead of pale yellow, even with Enchi possibly helping. Doubting the Pastel because the color is so vivid, there isn't strong blushing, and there isn't really strong squaring and horizontal squishing of the pattern.
My best guess for those two would be CG Enchi that have A+++ CG and Enchi with really weak pattern control.
Is the color really superior on your Mojave Fire Coral Glow het OG? Maybe pic of that parent or both parents would assist.
