Color conversion and contrast checking

Use HEX, RGB, HSL, and contrast ratios to keep interface colors readable.

Start with the smallest reliable input

Use color conversion with a short real sample before pasting a large payload. Smaller inputs make syntax, encoding, and formatting mistakes easier to see.

Keep sensitive data out

Browser-based utilities are useful for speed, but production secrets, private tokens, customer data, and internal hostnames should still be redacted.

Copy only after checking the result

Generated output should be treated as a draft until you confirm the target runtime, syntax variant, or platform behavior.
