Adjustment of button backlighting for colorblind users
To increase the contrast and visibility of buttons in the Ka50 cockpit I just made some changes to hue, or hue and saturation.
To install just copy the file into your DCSWorld\Mods\aircraft\Ka-50\Liveries\Cockpit_Ka-50 directory and extract it.
Rename the existing english folder to english_old so you have a backup.
Then rename the folder you extracted from english_colorblind to english.
To revert to the original button lighting just delete the new folder and rename english_old back to english.
Since these files are just EDs original files with tweak, I've noted they are not to be redistributed.
