Hex Editor Neo provides a feature called Pattern Coloring that can be used to automatically highlight specific patterns in an edited document. You define a pattern and specify the coloring applied to it in an editor window. Pattern Coloring fully supports regular expressions.
“Range Rule” type also allows you to specify a range in a document and coloring to apply to this range.
A Pattern Coloring Tool Window is used to define one or more patterns and coloring rules. For each defined pattern (or range), background color, foreground (text) color, outline color and rounded edges flag are defined. It is recommended to specify semi-transparent background colors. In this case, if several modules apply coloring to the same editor's cell, it is still possible to differentiate them.
