RGB ↔ HEX Converter
Convert browser color values between RGB channels and standard six-digit HEX notation.

How RGB maps to a six-digit HEX color
RGB stores red, green and blue as decimal channel values from 0 through 255. Six-digit HEX represents the same three channels with two hexadecimal digits each: #RRGGBB. Decimal 0 becomes 00 and decimal 255 becomes FF, so RGB(255, 0, 0) maps to #FF0000.
Worked conversion examples
RGB(0, 128, 255) becomes #0080FF: red is 00, green 128 becomes 80 in hexadecimal, and blue 255 becomes FF. In the other direction, #FFFFFF maps to RGB(255, 255, 255), while #000000 maps to RGB(0, 0, 0).
Where these formats are used
CSS, design systems and graphics tools often accept both RGB and HEX. HEX is compact for copying into stylesheets and design tokens, while RGB can be easier to reason about when adjusting individual channels. Converting the notation does not change the intended color; it changes how the same channel values are written.
Six-digit HEX versus other CSS color forms
This tool focuses on ordinary six-digit RGB HEX values. CSS can also use shorthand forms, alpha transparency, HSL and newer color spaces. A value with transparency is not fully described by only three RGB channels, so check alpha separately when converting assets or interface colors that are not fully opaque.
Why the same value can look different on two screens
A matching numeric conversion does not guarantee identical visual appearance on every device. Display calibration, brightness, gamut, color profiles and browser color management can affect what you see. For brand-critical work, verify the final color in the actual design environment and on representative displays.
Practical checks
- Keep RGB channels within 0–255.
- Copy all six HEX digits for the standard form.
- Do not assume RGB/HEX conversion includes an alpha channel.
- Preview important colors in the final interface.

How RGB values map to HEX codes
RGB describes a colour with red, green and blue channel values. In the common eight-bit format, each channel ranges from 0 to 255. A six-digit HEX code expresses the same three channels in base 16, with two hexadecimal digits for each channel: red, green, then blue. For example, RGB(255, 0, 0) maps to #FF0000, while RGB(0, 0, 0) maps to #000000.
Use converted colours in a design workflow
- Copy the RGB triplet or HEX value from the design system or colour picker.
- Enter it into the corresponding field and check that each channel falls within its valid range.
- Copy the converted value into the CSS, design token or editor that expects that format.
- Preview the colour in the actual background and component state before publishing.
For example, a design file may show an RGB value while a stylesheet uses HEX. Converting the format helps move the same colour between tools, but it does not decide whether the colour has enough contrast against its background. For interface work, check the pair with a contrast tool and inspect hover, focus, active and disabled states as well as the default state.
Alpha, rounding and display limits
This converter focuses on RGB and six-digit HEX. CSS also supports other colour syntaxes, including alpha transparency and wider-gamut spaces; those are not interchangeable with every six-digit value. A browser or display may render the same encoded colour differently because of colour profiles, brightness and surrounding colours. The conversion is mathematical, but perceived appearance is also affected by the viewing environment.
RGB-to-HEX questions
Does HEX support transparency?
A six-digit #RRGGBB value does not include alpha. Eight-digit HEX can express an alpha channel in CSS, but use that format only where the destination supports it.
Why are letters used in HEX?
Hexadecimal uses sixteen symbols, 0–9 and A–F, to represent each channel with two characters.
How to use RGB ↔ HEX Converter for everyday work and study
RGB ↔ HEX Converter is designed for freelancers preparing files or measurements for a client, remote teams working across different conventions, and students translating values between units or formats. For RGB ↔ HEX Converter, the real benefit comes from applying the output correctly, not merely seeing a number or transformed value. For RGB ↔ HEX Converter, enter source information carefully, then read the output in light of the assumptions that produced it. Use RGB ↔ HEX Converter as a focused browser step when a quick check would otherwise mean setting up a separate spreadsheet.
Worked example: RGB ↔ HEX Converter
RGB channels generally range from 0 to 255, while a six-digit hexadecimal color represents red, green, and blue in base 16. Verify channel order and any alpha setting separately because a six-digit hex code does not include transparency. Compare the converted color in its actual CSS or display context.
Start with the inputs, not the answer
Before running RGB ↔ HEX Converter, review the fields it actually uses, such as dates, units, text, quantities, or settings. A freelancer using RGB ↔ HEX Converter can document a quote, invoice, proposal, delivery estimate, or other client-facing result with the inputs that produced it. For a remote team, RGB ↔ HEX Converter can help inspect the input before it is translated into the team's agreed format or workflow. After completing the underlying work, students can use RGB ↔ HEX Converter to check one specific part of the answer without replacing their own reasoning. For RGB ↔ HEX Converter, an incorrect source value can still produce a misleading output, so review the original fields before relying on the result.
A practical US workflow
When a US freelancer uses RGB ↔ HEX Converter, retaining the source value beside the output makes the check easier to explain later. For RGB ↔ HEX Converter, note its relevant input, such as an amount, duration, text sample, unit, or setting, next to the output that the page returns. A remote teammate can document how RGB ↔ HEX Converter was used in a project ticket, letting colleagues repeat the same steps. For coursework, RGB ↔ HEX Converter works best alongside the original exercise: compare both to catch arithmetic, formatting, or conversion mistakes without skipping the learning step. Keeping the inputs with RGB ↔ HEX Converter's output gives a client or teammate a trail to review instead of a number with no explanation.
When the result needs a second check
If RGB ↔ HEX Converter is used for a contract, tax return, payroll choice, school requirement, or another consequential task, verify the result independently before relying on it. RGB ↔ HEX Converter can speed up a routine calculation or transformation, but it cannot infer special project assumptions or know every change made by an outside authority. Before acting on RGB ↔ HEX Converter's result, check its inputs, reproduce important figures independently, and ask the responsible organization about official requirements. RGB ↔ HEX Converter is a practical utility, not a substitute for professional advice or an official record.
Tips for repeat use
- For RGB ↔ HEX Converter, choose a unit and rounding convention and apply it consistently across the task.
- Save the inputs used by RGB ↔ HEX Converter alongside its output whenever a client or teammate may ask how the result was reached.
- Only provide RGB ↔ HEX Converter with information required for its task; leave out client secrets and unrelated confidential details.
- When sending a RGB ↔ HEX Converter result to a client, label estimates clearly and state the assumptions that matter.
- For an assignment involving RGB ↔ HEX Converter, follow the instructor's rules about permitted calculators, outside assistance, and submitted work.
Limitations and privacy
What RGB ↔ HEX Converter returns depends on the information supplied and the method implemented on this page. RGB ↔ HEX Converter may not cover every unusual input, local requirement, product-specific convention, or future change. If RGB ↔ HEX Converter displays live or external data, check the stated source and timestamp instead of assuming the value stays current. For sensitive work, use the minimum information necessary. The best way to use RGB ↔ HEX Converter is to understand the assumptions and verify consequential outputs rather than treating convenience as official authority.
