I suspect the "all red" as opposed to "only some red" is because the PSRed

The sirus-red stain is a stain to differentiate collagene I against collagene
III in polarized llight, so in bright field all fibres will be red, just if you
change to polarised light, you can differentiate both kinds of fibres by their
birefrigence which is orange to yellow for collagene 1 and
