There is a Gimp batch plugin BIMP see: https://alessandrofrancesconi.it/projects/bimp/
The BIMP commands are a bit meagre - Colour Correction is brightness / contrast but it also uses Other Gimp Procedures where you can use the Gimp Hue-Saturation function.
There is also a Gimp plugin gimp_gmic_qt from http://www.gmic.eu which has all sorts of filters, there is a colour swao for example. BIMP can use this plugin, again as a 'Other Gimp Procedure'
It can get a bit complicated to explain and I am packing in for the day, Have a look at BIMP and gmic. If you can post a few of those icons you have already done, before and after and I can make a procedure example for you.
