Figure 4. Color maps indicating functioning and non-functioning systems. Each letter represents different repressor binding site configurations. Each small square within the color maps represents a score for a simulation of the system with a unique set of parameters. The colors correspond to a working system (2:red), leaky system (1:green) and a non-functioning system (0:blue). The table underneath shows the configuration of the repressor binding sites. The type of repressor binding site is specified followed by the promoter it is located on. The letters correspond to the colormaps
