I'm working on a tensile sensor based image and I would like to create an equation to correlate pixel color to load. How can I do it without image processing toolbox? I have RGB colored image and the actual load at which that image was captured.
In the image below, the effective load is 500N.

Yup, I would definitely recommend calibration with known forces. And area of an object such as a penny should be easy enough to calculate especially as it is already known https://www.bluebulbprojects.com/measureofthings/results.php?p=1&comp=area&unit=in2&amt=0.442&sort=pr.
