Colors Bob

This dataset consists of colors prepared by mixing varying amounts of 5 colored dyes (red, orange, yellow, blue, green). The parameters represent fractions of each dye used in a mixture. The target is the normalized green-like RGB value [0.16, 0.56, 0.28]. Experiments are performed using the Bayesian Optimized Bartender (BOB). 1

The dataset includes 241 samples with four parameters and one objective.

yellow	continuous	[ 0, 1]	amount of yellow
blue	continuous	[ 0, 1]	amount of blue
green	continuous	[ 0, 1]	amount of green
