change interface colors

How can I change the color of viewports/cursor? They have same color and its very hard to spot

You can not change the cursor, inside Blender. (only through your operating system’s mouse cursor settings. in windows: control panel, mouse settings I think.)
But, you can change the color of anything else in blender by:

  1. Pulling down the top menu bar, by clicking and dragging down the horizontal line, just below it.
  2. Click the themes button. Now you can change the default theme to rounded. See if that works.
  3. You may make your own theme, and change whatever colors you want.

Here is a video tutorial to change interface colors.

After making the desired changes, press CTRL+U to save the settings. I forgot to show it in the video.
