Studio Products Gray Scales, Grisaille Sets, and Munsell...
SP's 1/2 gray scale: The Munsell scale is 3 to 3.75
SP's 1/2 gray scale: The Munsell scale is 2 to 2.75.
SP's 1/2 gray scale: The Munsell scale is 1 to 1.75.
SP's Value 5 gray scale.
I originally posted this over on Dead Color Diary and Graydon asked if I could post it here.
I decided to add photos so people can judge for them selves.
This is Value 5 gray: I originally thought they were at value 6 but I think it's closer to 6.25.
That's way off. On SP's web site they claim that: " Grisailles' perfectly neutral greys mixed to aprecise Munsell Value Scale". The chart is a gray scale done in quarter tones to Munsell. It is clear that they are not value 5 and far from 'precise'.
Testing is done on the 1/2 gray scale. I need to take better photos of them but it is clear that they are not right. The 1/2 came out to about 3.25. The issue for me is that SP has two values as one. Kind of silly as a concept. It's all for naught as they are wrong anyway. 1 is a very dark gray so low in value that it looks black. This booklet starts at 0.5 so 1 is a gray.
SP's notion that values 1 and 2 are so close as warrant this value as one is a lot more off than I originally thought. If you look at the values with a chart like this you see there is a huge difference between a value 1 gray, and value 2.
I have these on acetate the lines are a grid for another project.
Sorry about the lines, I ran out of acetate.
