Default Brake Fluid Color.....Green???

I am doing a complete brake job...replacing the seals and boots, new pads and rotors on all 4 wheels. I first disconnected the right rear brake line and let it drip into a white plastic tub, and then took the caliper off....after I happened to look into tub and the brake fluid is green.
Now I live in the desert Southwest and this vehicle came from Long Island...and I left Missiouri a long tme ago....but is there some kind of brake fluid that is meant for cold regions or something??? I have never seen green brake fluid before. The fluid at the master just looks black.

Thanks.

I seem to recall that the old formula Castrol LMA was green. The new formula (higher
boiling point) is a light tan.

I've seen brake fluid with a green tinge to it. Likely depends on the brand and if it's DOT4 or DOT5. If the fluid in you MC looks dark, you should be doing a complete fluid change. Actually, you should be changing it evey few years anyway.

Maybe ATE blue. Don't matter, flush it out completely.
