About RGBA to HEX Conversion

Understanding the conversion between RGBA and HEX color formats with alpha transparency

RGBA (Red, Green, Blue, Alpha) extends the RGB color model to include transparency:

• Red: 0-255

• Green: 0-255

• Blue: 0-255

• Alpha: 0-1 (0 is fully transparent, 1 is fully opaque)

For example, rgba(66, 135, 245, 0.8) represents a blue color with 80% opacity.

HEX with alpha is an 8-digit hexadecimal color code that includes transparency:

• Format: #RRGGBBAA

• The first 6 digits (RRGGBB) represent the color

• The last 2 digits (AA) represent the alpha/transparency

• Alpha values range from 00 (transparent) to FF (opaque)

For example, #4287f5cc represents rgba(66, 135, 245, 0.8).

Converting from RGBA to HEX with alpha involves these steps:

1. Convert each RGB value (0-255) to a two-digit hexadecimal number (00-FF)

2. Convert the alpha value (0-1) to a percentage of 255, then to a two-digit hex value

3. Concatenate all four hexadecimal values with a # at the beginning

For example, rgba(66, 135, 245, 0.8) converts to #4287f5cc:

• 66 in decimal = 42 in hex (Red)

• 135 in decimal = 87 in hex (Green)

• 245 in decimal = f5 in hex (Blue)

• 0.8 × 255 = 204 in decimal = cc in hex (Alpha)

HEX with alpha (#RRGGBBAA) is supported in:

• Chrome 62+

• Firefox 49+

• Safari 10+

• Edge 79+

For older browsers, it's recommended to use the rgba() format as a fallback.
