Color Chart

[trod]

Does anyone know where a color chart can be obtained that shows how other colors are related to 18% grey and the amount of stops over or under?

Not photographically , but the munsell color tree is pretty much a hue saturation lightness construction. If you set saturation to 0 the 18 percent lightness value ( I think ) is 18 percent grey . They are 3D models and expensive a quick google should have nice photos. Also help with a good understanding of color space.

If you get something like an X-rite color checker passport you can set exposure and wb for neutral grey and then over and under expose by stop intervals and see the effect on the color targets

Macbeth makes the industry standard chart. It's not cheap, but it's the one everyone uses.
