Hi all,
I am looking for the right model and right test desing to use for the following case:
I want to measure the colour of a flake material on a colour measuring device. There can be x (to be defined) different colours in the material. Standard material is blank.
Each colour I can measure in a dillution serie to make a calibration line for that specific colour y = ax + b
For multiple colours I than would use y = b0 + a1x1 + a2x2....
This approach however does not hold since within the measurement the different colours interfere with each other. I.e. I can make a perfect line with green and seperate one with red but if they are together in one sample they will give a yellow signal in y and my model will not hold.
So basically I would like to know what model I could use for this and what test design approach I can best use to feed the model with data.
Thanks a lot!
