Frame Pinto (O), also known as frame overo or overo, is a pinto pattern. Frames generally have dark legs. The white of a frame is concentrated on the sides of the body. Frames usually have have a white face. Blue eyes are common.
Frame is dominant, and thus cannot skip generations. All frames are heterozygous. Homozygous frames suffer from Overo Lethal White Syndrome (OLWS) and are known as Lethal Whites. Lethal White foals are born all white and die soon after birth due to an incomplete lower colon. Due to OWLS two frames should never be bred together. There is a test available for frame, the same which tests for OLWS. Testing is critical because some frames do not have any or very little body spots.

Several frames were photographed by The Rural New Yorker in 1940. However it appears to have disappeared a few years later. Frame again appears to have briefly existed in the feral herd at some point in 1960s. A frame mare appears on postcards from the 1960's, was captured on video in 1962, and appeared in a 1972 newspaper article. It likely would have been introduced through Mustang or Paint Horse outcrossing. It's also possible she may have been introduced due to the 1962 nor'easter as other breed introductions were done in the aftermath. No living Chincoteague has tested positive for frame to date.
