About RGB to HEX Converter
Each channel is written as two hexadecimal digits, so 255 becomes FF and 136 becomes 88. Values outside 0–255 are clamped rather than wrapped, because clamping is what every browser does and wrapping would turn a slightly-out-of-range red into a dark green. Percentage inputs are converted first, so `rgb(100%, 50%, 0%)` works.

Questions
Can every RGB color be written as hex?
Every 8-bit-per-channel color, yes — that is exactly what hex encodes. Wide-gamut CSS colors in `color(display-p3 ...)` cannot, because they describe colors outside what sRGB hex can name.
Should I use hex or rgb() in CSS?
Functionally identical for opaque colors. `rgb()` is easier to generate programmatically and reads better with alpha; hex is more compact. Modern CSS accepts `rgb(255 136 0 / 50%)` with slash-separated alpha.
