2. Eclipse background color modification
The default color of the operation interface is white. For those of us who use computer programming for a long time, white is very irritating to our eyes, so I often change the background color of the workspace to make the eyes more comfortable. The setting method is as follows: 1. Open windows->Preference-> General->Editors-> Text Editors, the Text Editors panel appears on the right. There is such an option in the panel: Appearance color options; which are the settings of various plate colors, one of which is background color, choose the color according to your own preferences.2. Select the background color, uncheck System Default, click 'color', the color selection panel will pop up, select the color you like, and click OK.
3. Go back to Text Editors and click Apply. Expand Test Editors, there are other options, such as the color style of the error prompt, if you are interested in this, you can try changing it.
Background color recommended to you: Hue: 85. Saturation: 123. Brightness: 205
documents are no longer dazzling black characters on a white background, but a very soft bean paste green. This color is configured by ophthalmologists . Long-term use will effectively relieve eye fatigue and protect eyes. 3. Character set settings
