Metamerism (vector-matrix representation of color perception)

Click For Summary
The discussion revolves around explaining metamerism using vector-matrix representation of color perception under different illuminants. The user seeks confirmation on their understanding of how two objects can appear the same color under illuminant A but differ under illuminant B. Participants emphasize the importance of defining variables and functions to facilitate better assistance. Providing standard references or links related to the topic is suggested for clarity. Overall, the focus is on accurately representing color perception in varying lighting conditions.

Homework Statement
I want to explain metamerism by using vector-matrix representation of color perception. So, here, there are 2 conditions where the both objects produce the same color with illuminant spectrum A, and the both objects produce the different color with illuminant spectrum B
Relevant Equations
in the picture below
For the illuminant A

You are much more likely to get help with this if you take the trouble to define the variables and functions. If they’re standard within the topic, perhaps you can provide a link.
 
I want to find the solution to the integral ##\theta = \int_0^{\theta}\frac{du}{\sqrt{(c-u^2 +2u^3)}}## I can see that ##\frac{d^2u}{d\theta^2} = A +Bu+Cu^2## is a Weierstrass elliptic function, which can be generated from ##\Large(\normalsize\frac{du}{d\theta}\Large)\normalsize^2 = c-u^2 +2u^3## (A = 0, B=-1, C=3) So does this make my integral an elliptic integral? I haven't been able to find a table of integrals anywhere which contains an integral of this form so I'm a bit stuck. TerryW
