+# 202_107: Fix python syntax visibility for dark theme
+
+### Issue :
+In the dark theme, the syntax of Python becomes difficult to see.
+
+### What
+To imrpove visbility updated the Python syntax highlighting color scheme in `python-lang.scm`.
+
+**Color Changes:**
+- Keywords: #309090 → #005CC5 (Deep Blue)
+- Constants: #4040c0 → #D73A49 (Soft Red)
+- Strings: dark grey → #22863A (Medium Green)
+- Functions: #0000c0 → #6F42C1 (Muted Purple)
+- Classes: #0000c0 → #B31D28 (Deep Red)
+- Operators: #8b008b → #E36209 (Warm Orange)
+- Brackets: #B02020 → #E36209 (Warm Orange)
+- Comments: brown → #999999 (Neutral Gray)
+- Errors: dark red → #CB2431 (Strong Red)
+- Field Operator: #88888 → #999999 (Neutral Gray)
+- Special Operators: orange → #E36209 (Warm Orange)
+- Undefined: red → #999999 (Neutral Gray)
+
+Python syntax is better visible on both light and dark themes with improved contrast and visual distinction between different syntax elements.
