Is it possible to change the black colors as shown in the picture? The black check mark, circle, and the borders of the check boxes and radio buttons, specifically.
It makes my color scheme look bad. 
Hi @Iokaar, which browser are you using? On my side in chrome this does not seem to be the case.
I am also using Chrome.
Could you try it in an incognito window where all extensions are disabled? Perhaps something is interefering with it.
OK, tried incognito mode, but I still have the same issue. I even tried changing the color to see if it changes.
Does not change in the app either:
Edit: I tried Firefox as well. It closer, but the borders are still black.
Microsoft Edge:
And these radio buttons and check boxes are also appearing this way when you preview the app and on the published version? Could you share a link with me of the published app so I can check that too? I’m not really sure why it would be this way for you other than something interfering with the CSS in your browser. Can you try clearing your cache for Baserow, it could resolve it and it’s the only idea I’ve got left.
I edited my post to show the result in different browsers. I noticed its closer on Firefox and the border width is also correct on Firefox, but not an any other browser. I cant publish the app because I don’t have a domain for it yet (and I am on free version as the features are not there for me to pay yet).
App preview in Chrome:
App preview Chrome Incognito:
App preview in Firefox:
App Preview in Edge:
I tried changing my secondary color, which looks like the gray color on the Firefox preview, but the border color still remains gray/black.
Firefox and Edge have no add-ons or anything. They are as they would be if you just installed them. “Stock” browsers, if you will. 
Hi @Iokaar, I’ve checked and found that it’s not currently possible to customize the color of radio buttons or checkboxes.
Here’s the issue to fix that: Radio/Checkbox Color Customization in Application Builder (#3565) · Issues · Baserow / baserow · GitLab
