How do I change number and bracket colors in the arduino IDE?
Inside path C:\Program Files (x86)\Arduino\lib\theme\syntax there is file default.xml where I made some changes and the following lines are as follows:

  &lt;style token="SEPARATOR" fg="ffffff" /&gt;
  &lt;style token="LITERAL_NUMBER_DECIMAL_INT" fg="ffffff"/&gt;
  &lt;style token="LITERAL_NUMBER_FLOAT" fg="ffffff"/&gt;
  &lt;style token="LITERAL_NUMBER_HEXADECIMAL" fg="ffffff"/&gt;


After this brackets and numbers occur white.
