Infrared23 is RED.
I'd say from lightest to darkest red shades:
Infrared
Challenge Red
Infrared23
Fire Red
Varsity Red
These are based on colorways I own. The Infrared23 looks pinkish w/out flash and very red with flash. In person it's between the two. It's a tad bit lighter than the Jumpman logo on the box, if not exactly that shade. I've learned to stop judging on pictures and judge in person.
The white infrared is very pinkish---but that is how the original 1990 pair is---and that's also what you purists asked for, and now, you have it.
I label this 6 as an instant classic the same as the Toro 4 and 5. I think the next shoe to get the all red treatment will be the 13, with black pods on the bottom of the shoe.
