Collomia tinctoria (Staining collomia) is a native California herb in the Polemoniaceae family, recognized by maroon-violet tube with pink lobes and awned calyx.

Staining collomia is a California native annual found in the Klamath Ranges, northern California Coast Ranges, Sierra Nevada, Transverse Ranges, and Great Basin in gravelly to rocky open areas at elevations of 600 to 3,000 meters. Flowering from June to September, this plant produces delicate pink and maroon flowers with blue pollen in small clusters of two to three blooms. Growing with slender stems 2 to 8 centimeters tall, the plant has distinctive spreading branches covered in long translucent glandular hairs. Its lower leaves are narrow and linear, glandular to the touch, and positioned along the stem with relatively long internodal spaces. The flower's unique color combination of maroon tube, pink lobes, and blue pollen makes this tiny annual a distinctive find in its rocky mountain habitats.
