Cause of Color Loss

I baled Timothy last week, and was cut probably a week later than I wanted to so it had lost a little glow, completely headed out but still green no brown dryness at all, cut it Teddered it two days in a row bein so tall and thick and went to rake it the day I figured it was ready, decided it wasn’t, came back the next day and baled it all at 12% average. Took a day longer to dry than I normally wait but the color just wasn’t great on it, had lost a lot of that light green color I’m used to. So I guess my question is is this more of a maturity problem or the 90 somthin degree heat, or maybe I should have went with my gut and baled it the day before. What do y’all think?
