Colors for plotting GTEx data

A custom palette used by Wang and Stephens (2021) to plot an empirical Bayes matrix factorization of data from the GTEx project (of which the gtex data in package flashier is a subsample). The palette is designed to link similar tissues together visually. For example, brain tissues all have the same color (yellow); arterial tissues are shades of pink or red; etc.

Format

gtex_colors is a named vector of length 44, with names corresponding to tissues (columns) in the gtex dataset and values giving hexadecimal color codes.

Examples

fl <- flash(gtex, greedy_Kmax = 4)
#> Adding factor 1 to flash object...
#> Adding factor 2 to flash object...
#> Adding factor 3 to flash object...
#> Adding factor 4 to flash object...
#> Wrapping up...
#> Done.
#> Nullchecking 4 factors...
#> Done.
plot(fl, pm_colors = gtex_colors)
