RGBA to HEX Converter

The RGBA to HEX Converter transforms RGBA color values into hexadecimal format. The RGBA to HEX Converter is widely used by web developers and designers who need to convert between different color formats. Our RGBA to HEX Converter ensures accurate conversion with support for alpha channel transparency.

How the RGBA to HEX Converter Works

RGBA to HEX Converter Color Space

The RGBA to HEX Converter processes each color channel as follows:

R,G,B∈[0,255]∩ZR, G, B \in [0, 255] \cap \mathbb{Z}
α∈[0,1]∩{x∈R:precision(x)≤2}\alpha \in [0, 1] \cap \{x \in \mathbb{R} : \text{precision}(x) \leq 2\}

RGBA to HEX Converter Formula

1. The RGBA to HEX Converter RGB conversion:

HEXRGB=toHex(R)+toHex(G)+toHex(B)\text{HEX}_{RGB} = \text{toHex}(R) + \text{toHex}(G) + \text{toHex}(B)

where toHex(x)=padStart(x.toString(16),2,′0′)\text{toHex}(x) = \text{padStart}(x.toString(16), 2, '0')

2. The RGBA to HEX Converter alpha handling:

HEXα=toHex(⌊α×255⌋)\text{HEX}_{\alpha} = \text{toHex}(\lfloor \alpha \times 255 \rfloor)

3. The RGBA to HEX Converter final output:

RGBAhex=#RRGGBBAA\text{RGBA}_{hex} = \#\text{RRGGBBAA}

where RR, GG, BB, AA are two-digit hexadecimal values

RGBA to HEX Converter Example

Using the RGBA to HEX Converter with: rgba(255,0,128,0.5)\text{rgba}(255, 0, 128, 0.5)

1. The RGBA to HEX Converter processes RGB values:

  • 25510=FF16255_{10} = \text{FF}_{16}
  • 010=00160_{10} = \text{00}_{16}
  • 12810=8016128_{10} = \text{80}_{16}

2. The RGBA to HEX Converter processes alpha:

  • 0.5×255=127.50.5 \times 255 = 127.5
  • ⌊127.5⌋=128\lfloor 127.5 \rfloor = 128
  • 12810=8016128_{10} = \text{80}_{16}

The RGBA to HEX Converter result:

#FF008080\#\text{FF}\text{00}\text{80}\text{80}
