huh, it does look like it doesn’t work anymore. Maybe you could try something like Nvidia game filter to increase the contrast on screen/shift the colors?

Another post with more information if you like.

I found [this] thread. It looks like you can open the console and type:

dota_enemy_color_r 0

dota_enemy_color_g 0

dota_enemy_color_b 0

and replace the zeros with the corresponding RGB value.
