The article focuses on the two multicolor labeling system for flies with versatility of Brainbow such as Drosophila Brainbow (dBrainbow) and Flybow. It says that the dBrainbow was based by S. Hampel and colleagues on Brainbow 1, but the first fluorescent protein gene was replaced by a transcriptional stop cassette. It adds that combining the GAL4 expression pattern with Flybow will give the opportunity to fine-tune the group of cells which will be expressed in proteins of different colors.
