If r, g, and b are the components of a color according to the Ives colorimeter, and R, G, and V are its values in terms of the elementary excitations used in this Report; | |
R=1870r+2080g+ 14 b | |
G=134r+3710g+ 124 b | |
V=506g+3460 b | |
Conversely:. | |
r=1275R− 719G+ 21 V | |
g=−46R+ 646G− 23 V | |
b=7R− 95G+ 665 V | |
There is an arbitrary factor in all of the above coefficients, so that the results are significant only as proportionalities. |

Coefficients for Interconverting Ives Colorimeter Data and Excitation Values
If r, g, and b are the components of a color according to the Ives colorimeter, and R, G, and V are its values in terms of the elementary excitations used in this Report; | |
R=1870r+2080g+ 14 b | |
G=134r+3710g+ 124 b | |
V=506g+3460 b | |
Conversely:. | |
r=1275R− 719G+ 21 V | |
g=−46R+ 646G− 23 V | |
b=7R− 95G+ 665 V | |
There is an arbitrary factor in all of the above coefficients, so that the results are significant only as proportionalities. |
