Agree with Bobby De La Rue. The Scott catalogue calls the basic color "rose".
Note that your link quotes a catalog value, which are always idealized valuations; most stamps sell for quite a bit less. Your stamp is toned at the top, is missing perfs at right and has a small tear at left. Any one of those faults reduces the value tremendously. In addition, the stamp design is badly centered, normal for the issue but catalog value reflects a much better centered stamp. This stamp can still be collected, but it's just not worth very much.
I strongly suggest you put behind the thought that you will find expensive rarities among your stamps, or even that you have the best variety. In any case, once identified here, you can go to
ebay to research for yourself for what stamps are actually being sold for and not what they are being offered at. Stamp collecting much less any collecting area is not for beginner treasure hunters.
