Legibility

Contrast: is #FE0000 accessible?

Black text on it reaches 5.21:1, passing AA. White text manages only 4.02:1, enough for large text only.

WCAG 2 gives the same ratio whichever color is the text; APCA does not, so its Lc changes sign and size with polarity.

Mixing

Mixing #FE0000

Each row is the same mix worked out in a different space, with the halfway color at its end. sRGB, which older CSS gradients use, can sag gray or dark in the middle; OKLab keeps the lightness steps even; OKLCH holds chroma and hue as it goes.
