Oxblood is red glass. Temperature effect usually....not always though
Pelt has oxblood but it is a bit different than akro. It's supposed to be red and gets an actual dried blood color.
MK, same thing, they make red then, at times, you get an oddball color to the red that is called oxblood.
The problem is (No slight to my friend Galen of course) is tunnel vision.
Look at a brick and look at an Akro milky or silver ox. the color is SIMILAR but not the same, but both are Oxblood.
A brick, to me, is the TRUE oxblood color as I understand what a color pallet is and while i prefer Akro over it, those are "similar" but the effect is more like blood on water and I like that look better.
Oxblood is a shade of red, nothing more.
This is oxblood
