[Alphacocoa-devel] [alphacocoa:tickets] #229 Selected text is invisible, depending on highlighting settings in System Preferences

[Bernard D. <bde...@us...>]

I see that.
This is because Alpha applies its own coloring schemes in the text area in order to control syntax hilighting. As you know, even when Dark Mode is on, Alpha's document windows retain their current foreground and background colors (black and white respectively by default).

I just tried to manually exchange these colors (background now black, foreground now white) and in that case Graphite selection works fine. But the problem is that syntax hilighting can become ugly and hardly readable.

Experimenting a bit more, I found that keeping a black foreground and setting a light gray (80%) background gives good results. These colors can be set using the preferences called *Foreground Color *and *Background Color* located in *Alpha Menu -> Preferences -> Global Preferences -> Appearance*. Note that the changes are not applied immediately on already opened windows: close the window and reopen it to see the changes.

I must think more about this before I can propose an acceptable solution...

If the Highlight colour, set in System Preferences →  General, is `Graphite` then the highlighting Alpha uses when text is selected is white, the text is white and they are invisible on the default white background. Selecting text effectively makes it invisible in the GUI. Chosing `Blue` as the highlight colour works around this bug. Possibly relevant: Dark mode is active. Reproduced on two different machines running different versions of macOS.
