Field Colors / Background (f. e. Log-In)

I am setting up a new page with the great Musician Template from JP ( Demo ) and have trouble finding the place where to change the colors for that special fact: the Log-In form in my set-up and in the demo as well becomes white when I click it and the text typed into that form is also white and therefor not readable. Where can it be changed? It's the same if authors hand in articles through front end.

I think I need help on that!

Thanks and keep up great work!

The link color can be changed in customizer
>> select your style
>> Advanced
>> Base ( more) > Link Color

Thanks for the reply. I got more into editing the styles in backend but still have some minor changes to make. For example I wand the color of the text change from white (which it actually is set to) to black when I do a mouseover or it is activated (light-green). The textz should be readable much better if it's black on light green instead of white on green-light. I could get it with Contrast Color in Typography but not on 1st level on menu.

PS.: I got all together along with your template so much that I will for sure next time check one of yours again! had much more trouble with another template of joomlaxtc before and that I skipped for that reason!

PPS.: Ich hätte eigentlich auch im Deutschen Forum posten können, wäre evtl. einfacher gewesen! *grins*

Ich würde den Customizer außen vor lassen und nur das nötigste damit machen.
Am besten sie machen alle Änderungen via custom.css
