If you don't own a particular set that I own, I can make you a PhotoShop color swatch for either specific colors or sets that I own. (I own every color the following list of brands makes).
This is a list of the Brands of Color Pencils I own (doesn't include Watercolor Pencils): Caran D'Ache - Pablo (Individuals very expensive + Best Blues), Faber-Castell - Polychromos (Best all around + Reds), Derwent - Studio, Coloursoft, Drawing (Both Awesome), Lyra - Rembrant Polycolor (Excellent - using more and more), Prismacolor - Premier, Artstix, Verithin (Softest Pencils - Premier has most colors, over 150, Verithin and Artstix kust a different form of Premeir for backgrounds or detail) and Dickblick Colored Pencils (which are "Koh-I-Noor" Colored Pencils made for DickBlick - These are very cheap, Lightfast and not bad at all believe it or not. I mostly use for mock-up but a few colors are used in finished work. Example: The DickBlick Pink Rose is more lightfast than the Studio or Artist Pink Rose and almost looks identical.)
I've found that sometimes certain companies create certain colors very well. For example: Polychromos (one of the most balanced 120 sets out there) have the best Reds, Caran D'Ache Pablo - have the best blues - Bloody expensive though, for Individual!! Prismacolor has over 150 colors but their manufacturing sucks these days. I still use them though, becaus3... they have such a awesome range of colors you that you can't get anywhere else and are the softest pencil made. Derwent Drawing Pencils are a very soft wax pencil - perhaps as soft as Prismacolor Premier.
If you don't own the Derwent Drawing 24 Pencil set, I highly recommend them! Even though they are 100% Wax compared to the Artist/Studio Pencils which are Clay/Wax and Harder, they work wonderful together and they have such a beautiful de-saturated palette.
Sorry for all the reading I caused you but I really appreciate what you created and shared. I feel like I owe you one. I would not have looked into the colors I'm asking you about had you not made the swatch that in return, allowed me to see how beautiful this Palette range truly is. Granted I love my Studio Pencils but there is a huge difference between 72 colors vs. 120, especially for flesh tone variations.
