.vlt

Panasonic's 3D LUT format: the header, then one R G B row per grid point, shown in their channel colors.

Loper is a free, minimal editor for macOS that opens Panasonic VLT look (VariCam, EVA1, LUMIX) instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
