Do ‘red’ and ‘redness’ mean the same thing? That is, color red is quality redness?
Red: red color
Redness: the quality or state of being red
1 Answer
"Red" is most often used as an attribute:
A red apple. Her face was red. A big red light.
You could not replace the adjective "red" with "redness" in these examples.
As a noun it is the name of a colour.
Crimson is a dark red.
And it is used to mean "a red thing" in a variety of contexts:
Would you like the red [wine]? There are reds [communists] everywhere. He potted a red [ball in snooker]
"redness" isn't the name of a colour. You can use it to describe how red something is:
The redness of the room is shocking!
or often to talk about medical inflammation
Redness of the skin can indicate an infection.

Then, ‘dark red’ is correct and ‘dark redness’ is wrong because ‘redness’ is something is red, not red itself.– user135277Commented May 2, 2021 at 20:38

1Dark red is correct. Dark redness would be rare (if the redness in the inflammation was also dark for example)– James KCommented May 2, 2021 at 20:45
