This is Part 3 of the series on changing Windows console colors to match your Leo theme.
This post is Part 3, the last part, of the series on making and using Windows console color themes. The ColorTool.exe program (see Part 1) makes it relatively easy to modify an existing theme. To create one from nothing would be very tedious. Assigning the text foreground and background colors is fairly easy once you know them. The hard part is to find good other colors, such as highlight colors, selection colors, etc. It's hard even to know which color name to use for assigning the other colors. These other colors can be important if a program issues special terminal emulator commands to print text in some other color, such as red for a warning. For my solarized dark theme, for example, I took the solarized_dark.itermcolors file that came with the ColorTools program, and changed only the text and background colors a little. I have attached a Leo outline with a few scripts to make the process easier. Run them with <CTRL-B> after changing their color values to suit yourself. I used each of these scripts as I tuned up the color theme files I attached to the Part 1 post. 1. Styles: get colors from palette This script gets the text and background colors from the current focused editor window and prints their CSS hex values to the log pane. This gives you a starting point if you have a Leo theme whose colors you like. 2. Rescale CSS Colors This script lets you change a CSS hex color by a given factor so that the color will be darker or lighter than the starting color. The new and old CSS hex values are printed to the log pane in their respective colors. Using a scale factor < 1 makes a color darker, and > 1 makes it lighter. The scaled r,g,b color components are limited to "ff", which prevents overflow if the factor is too large. Note that if any of the components are clipped in this way, the color hue may change noticeably. The scaling does not preserve the hue perfectly, but for small scale factors the new hue is not far different from what it would ideally be. (Ideally we would do the scaling in HSV space and then convert back to RGB, but it's probably not worth the trouble here). 3. Show CSS components in Decimal To change a color in the console Properties dialog, you need to know their decimal red, green, and blue components. You also need to know them if you want to edit the color .ini files directly. This script takes a CSS hex color string like "#4a5d63", and prints its r, g, b decimal components to the log pane. In this example, the components are '74 93 99'. Once you have changed the console colors using the console's Properties dialog, click on the "OK" button. Then you can use the ColorTool program to save them to a file. Assuming that you have changed the current directory to the ColorTool directory, the command is ColorTool -o schemes\<name>.ini where <name> is whatever file name you like. The file name must have a ".ini" extension, such as "new-dark.ini". (The ColorTool program can use several file formats including a JSON and an XML file format, but this way of saving the console colors produces an .ini file format). -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
