When I identify a color shade, my first rule is get a bunch of them and compare them. You have a few, and since you took the photo of all of them at once, it seems likely that they are different color shades of red.
The Stanley Gibbons Catalogue lists three color shades for this stamp:
Carmine-Rose, Bright Rose-Red, and Rosine with a date of 1901 for the earliest use.

Your stamps seem to be organized showing at least two and maybe all three colors. The bottom one seems to be the Carmine-Rose, the middle one appears to be the Bright Rose-Red.
The top one may or may not be Rosine but it has a 1903 cancel on it, so it is at least possible.

I would put them in my album with those identifications and then look for something that is a better fit.

Color is always subjective, and unless you are selling them as a specific shade - there is no penalty for being wrong. Make sure you check the watermark. There are inverted and reversed watermarks on these stamps which are way more valuable than any of the color shades.
