Although there are few images showing submarine chasers in camouflage paint schemes, there was some experimentation. These documents from the National Archives, Washington, DC, detail some planning and testing around camo schemes for chasers. Thanks to Aryeh Wetherhorn for sending the image scans to The Subchaser Archives.

Note that there are a few photos showing chaser in camo on the site.
