About the Variable Symbol color outline icon
A rounded browser or app window with a title bar, holding a pair of large curly braces that enclose an x character. Together they read as a declared variable, a code block or a mathematical unknown. Works well in developer tool interfaces, programming course pages, API and documentation sites, math or e-learning apps, and slides about algorithms and data types.
The braces are drawn with tall tapered curves and equal counter-space either side of the x, which sits centered like an algebraic term. The empty title bar keeps the frame neutral. It pairs with code brackets, terminal, function and database icons; give it a 4px inner margin so the braces do not touch the window edge.
This is the colour outline version of the variable symbol icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
