It is perfectly normal to have different filament settings for different colors of the same brand.
Each color has unique chemical and physical formulas. The colorant can drastically change the behavior - not just temp but many other things like stringiness, all the toughness and strength issues and many more.
It becomes even worse when you go between brands as each has their own proprietary blend of plastics. PLA isn’t PLA. It’s a BLEND. You have to understand that the filaments we’re using are complex polymer science, and the blends are industrial secrets that can be worth millions.
That is why to get the best prints from you machine you need to run Calibration tests for each brand and color the first time you get that one and SAVE it as a new, renamed, Profile like:
MatterHacker PLA+ Red .6 Nozzle (include the nozzle size, it matters)
Welcome to the wild and wonderful world of 3D printing. 
BTW - I wrote a (rather long, that’s my style) post you might read about Calibration and Bambu Studio vs OrcaSlicer (which is what a lot of people on here use instead). It’s here:
