Collinsia tinctoria is often on scree slopes and in full sun. Most populations are on the western Sierra Nevada and the Cascade Ranges. There are a few populations in the southern North Coast Ranges (Sonoma County) and at Mount Diablo (Contra Costa County). The reduction of the banner and the rearward projection of the pouch beyond the calyx are two floral traits that distinguish it. The mottled leaves of C. tinctoria are unique in Collinsia.
