The default color of fonts and symbols inside the equation environments in Kile is pale green, which is not very pleasant to my eyes... Is there an easy way to change this?
In the main menu of Kile, choose Settings and then Configure Kile. A window opens, in the left navigation tree choose Editor, Fonts & Colors. Then, on the right, click Highlighting Text Styles. Look for Math and change the green color to another one. Just double click on the green area next to Math and choose the color in the following color dialog.
