Winsor & Newton 006
PR108cadmium red deep*
cadmium scarlet
cadmium red light
Winsor & Newton 006
On Winsor Newton they seem to be the same number with a different name.

Most manufactures have a facts page and give the pigment numbers, color charts, etc. Google is a good research tool as well: as long as you do a good research and don't stop at the first solution. Lots of bad info around the web.

For color info this this site:

The Color Index (in this case PR108) indicates that this is the same pigment regardless of the different descriptive names. But this doesn't make much sense in the case of W&N. There is obviously a difference between cad red light and cad red deep.

I don't know what the asterisk signifies.

From my understanding PR108 comes in different shades even though it has the same label.

Actually, Winsor Newton now have a Cad free Scarlet and a cad free deep red and they are different numbers and different hues.

There are different processing (heating and addition of other elements, etc.) of the pigments that result in different hues of the base pigment. Hence PR108 Cadmium Red, is common to Cad Red Light, medium, deep, vermillion, scarlet, or whatever else the Mfg. decides to name the color based on the chemical composition of PR108. I would imagine that not all pigments are created equal, depending on quality/ purity, because from my experience, colors of the same name / pigment number vary from Mfg. to Mfg., and behave differently. I stick with one or two MFGs per single pigment color(s) so I know what to expect in mixes. Particularly with Cad Yellow Lemon/pale, my opaque primary yellow.

Thanks for all the info, and I do use, have consulted Art Pigment data base for years. My error--I didn't ask for the info I wanted, which I think, is, if the two hues, cadmium scarlet and cadmium deep, are side by side, will those hues be similar/the same?
I have cad deep, and one artist highly recommends cad scarlet🤔

It depends on the brands. If they’re both from the same brand they should be different. If they’re from different brands then they could be anything.

Blick has color swatches on their site for the brands they carry. Its not as good as seeing them in person but you compare the colors there.
