Lights out
Juan,
I always appreciate your insights and your knowledgeable aplication of them in your work. I agree totally with your points regarding the confusion of pigment names.
Reilly used as his basis the basic Munsell terminology but adapted it solely for classifying pigments. Munsell used theoretical black and white values. In his system white paint was actually around value 9.5 while black was 1.5. The Munsell system had to encompass all color measurement (fur, metal, etc.). So that is the rationale for the wider range.
Reilly made white=10 and black=0 with 5 in the middle. So obviously you go up in value to get to the middle from black. The usage of black as the highest number notation comes from the printing industry where more black ink equates a darker tone. It does seem illogical when talking about light since a 100 watt bulb is brighter than a 50 watt bulb.
In both systems, black and white are separated by nine equal steps of value.
I think sometimes people change certain terminology so they won't be accused for copying others' works. Who knows who copied who, Ross or Munsell. Ross's name sounds familier. I'll have to check it out.
Chroma is the measurement of steps from neutral. Cad red light is chroma 14 while neutral gray is 0 chroma. This is in both Reilly and Munsell so I don't understand why they can't be compared. This is new to me.
Off topic but how did that varnish turn out?
Take care.
