Eclipse is a default, and a background color is white, but many developers uses the dark color (black) and thinks whether it is used the letter color with white or green. I can't find tools which the color template can change an editor color of Eclipse by a blow very much. Do you know featured WEB sites.?
If get possible to choose dark color among a beginning like MIFES, makes me Happy
I don't fully understand your question but for changing Eclipse's editor background color just go to menu: Window > Preferences, and in the dialog go to General > Text Editors. In that form just select Background color from the list Appearance color options and use the color picker in the right to change it. For other formatting options go to General > Colors and Fonts in the same dialog.
NOTE: All these formatting changes are saved in your workspace if you create a new one it'll start with the default settings
If you mean "themes" as Netbeans has "Dark pastels" theme - then Eclipse currently doesn't have this feature.
