Frequently Asked Questions
How do I convert RGB to HEX manually?
Convert each R, G, B value (0-255) to its two-digit hexadecimal equivalent and concatenate them. For example, RGB(255, 87, 51) becomes #FF5733.
What is the valid range for RGB values?
Each R, G, B component must be between 0 and 255. Values outside this range are invalid.
Can I use the HEX output directly in CSS?
Yes. The output is in the format #RRGGBB which is valid CSS syntax for color properties.
Can I use the HEX output in Tailwind CSS?
Yes. Add the HEX colour to your tailwind.config.js under theme.extend.colors to use it as a custom colour class.
What is the HEX code for common colours?
Red: #FF0000, Green: #00FF00, Blue: #0000FF, White: #FFFFFF, Black: #000000, Yellow: #FFFF00, Cyan: #00FFFF, Magenta: #FF00FF.
Can I convert RGBA to HEX?
Standard HEX (#RRGGBB) does not include alpha. Use 8-digit HEX (#RRGGBBAA) for colours with transparency.
How do I find the RGB value of a colour in CSS?
Use browser DevTools: right-click an element, inspect it, and click the colour swatch in the Styles panel to see and convert the colour value.
