gtex_colors {flashier}

Colors for plotting GTEx data

Description

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.
