Notes

The official C++ logo (created by the ISO C++ Foundation) features a hexagon with these three blue tones and white lettering.
The color scheme was chosen to feel trustworthy, professional, and technical — similar to C’s palette but deeper and more saturated.
Many editors (VSCode, JetBrains, GitHub syntax highlighting) use variations of blue and gray for .cpp and .h files in line with this aesthetic.
