HEX byte → decimal RGB channel

RGB channel → two-digit hexadecimal byte

Substitution steps

1. HEX → RGB
hex bytes → decimal channels
= rgb(26, 115, 232)

Computed example results

RGB: rgb(26, 115, 232)
HEX: #1A73E8

Understanding the result

Read the main result together with supporting checks, assumptions, limits and intermediate values.

For a manual check, repeat the first equation, confirm the units and change one input at a time.

Assumptions and calculation scope

Conversion is assumed to match the real case. Choosing a different available option can change the method, factor or interpretation used by this calculator.
Color Converter applies the displayed HEX byte → decimal RGB channel relationship to the entered developer & programmer inputs. Factors that are not exposed as inputs or stated assumptions are outside this calculator's calculation scope.
