Introduction

It is possible to change how languages are highlighted. Within the IDE, select Tools > Options (or shift-control-d [shift=option-d on Mac) A dialog box will appear. These options are in Editor > Display > Colors.

One color scheme defines the color for all languages. However, in the options, you can specify which scheme to use language by language by using the second drop down menu. So you may override the language highlighting for one specific language by choosing a theme just for this language even if you don't use the rest of the color scheme.

Adding custom schemes

There are many color schemes available by default. However an additional color scheme can be described by an XML file. Additional schemes can be added by copying them into a folder called "userschemes" in the primary-config-path. The sub folder "userschemes" must be created if missing. The list of schemes is determined on Lazarus startup.

To know where the folder is, click on the icon to save/export the selected scheme from the IDE (after the scheme drop down menu). This will popup a dialog with the directory of custom themes. The location may change if you have multiple installations of Lazarus.
