The Best Invention Ever?

While browsing the internet for design sites that I could use for inspiration, I found this picture. I followed it to the creator of the product, and was instantly excited! I am unsure if this has been on the market for a while, or if it is brand new, but either way, it is genius!

The PANTONE Skin Tone Guide was designed for a number or reasons, but you can also use it to find the perfect skin tone to make adjustments to photos or other designed materials. According to the PANTONE website the guide, which features 110 colors for $89, can also be used in beauty, fashion, medicine, printing, product design, and photography. They came up with the colors by "measuring thousands of actual skin tones across the full spectrum of human skin types".

While I don't see myself purchasing this yet, I do think that it is a great idea, and a wonderful invention.

Would you use this? Do you think it is a good idea, or something that you would probably never need to use?
