TMI is a tool for making basic color temperature adjustments on TOPs. It is written in GLSL.
TMI features a color temperature slider (T), a magenta/green shift slider (M), and an intensity slider (I).
Input textures must be in a linear color space. The OCIO TOP is a great way to achieve this if using an sRGB or other display referred color space source. The see the attached example toe file to see this practice in context.
Thank you to Stefan Ihringer for posting the necessary math on his blog.
