Replacing the const uint32_t color values with static constexpr uint3…

[RealTimeChris]

Summary

Converts all color constants in the colors namespace to constexpr, enabling compile-time evaluation and optimization.

Changes

• Added constexpr to all color constant declarations
• No functional changes - purely optimization

Benefits

• Compile-time evaluation: Colors used in constant expressions can now be computed at compile time
• Dead code elimination: Unused color constants can be completely eliminated by the compiler
• Better inlining: constexpr enables more aggressive compiler optimizations
• Zero runtime cost: No performance impact, only improvements

Code change checklist

• I have ensured that all methods and functions are fully documented using doxygen style comments.
• My code follows the coding style guide.
• I tested that my change works before raising the PR.
• I have ensured that I did not break any existing API calls.
• I have not built my pull request using AI, a static analysis tool or similar without any human oversight.
