Pergunta
I searched on the web to change the color of differentiation block border in Compare editor of eclipse(Juno). I tried change through the Preferences>appearance>Colors and Fonts, But it doesn't has block border color to change.
In the above image, showing comparing differences with a white border, I want change it to blue.
Can any one please tell me, How to change differentiation block border color?
