FTPro - Custom Rainfall and Temperature scales

Master TMOMaster TMO
in Mapping with ProFantasy's Software
I'm doing a quickie project using FT Pro, and I would like to export a grayscale version of the Rainfall and Temperature maps for the world. For Altitude, I can create a custom color list in the .lgt as a text file, but the .bcl file for Rain and Temp appears to be a binary. Is there an easy way to create my own custom color files for these?

I know I can do it by hand through the dialogs, but it is *extremely* difficult to do a 256-color shading manually.

Thanks in advance,
TMO

    It's not so hard to do if you use a non-obvious feature of FT. On the rainfall tab of Lighting and Color, set # colors to 256. Then click the Lowest box and select black. Then, while holding down the Shift key, click on the Highest Value and (still holding down the Shift key) click white. The color list should be a full grayscale value.

    This technique works for any two colors, because Shift triggers use of full RGB colors rather than the more limited Campaign Cartographer palette when picking and interpolating colors. Doing the above steps without holding down Shift will get you a 16-color step (colors picked from the CC palette); holding down Shift gets the full 256-color RGB ramp.
