But, the observations belonging to one unit (color) exhibit a negative relationship - this is what we would like to identify, because this is the reaction of $y_{it}$ to a change in $X_{it}$. The most important practical difference between the two is this: Random effects are estimated with partial pooling, while fixed effects are not.
