While the trich color is the best way to determine when to harvest, it's important to look at other other clues Mary gives you. From your pics, most of your hairs are orange. which indicates it's towards the end of your optimal harvest window. Your trichs say "I'm not done yet" but your hairs say "I'm well-done".

My suggestion would be to take a small sample and flash dry it to see if it's the consistency you want. I despise couch-lock from my smoke, so I make sure not to harvest too late. You can always flower it longer if you want more body high, but you can't "un-flower" if it it's too much.
