About RGBA to RGB Converter
Input an RGBA value like rgba(0, 255, 255, 0.5)
and Diversify India’s RGBA to RGB converter will convert this value to an RGB color like rgb(128, 255, 255)
.
Additionally, we can even specify a background color in RGBA format. Diversify India’s RGBA to RGB converter will mix these foreground and background colors to get the resultant RGB color.
RGBA color parameters are red, green, blue, and alpha. The output RGB color parameters are red, green, and blue.
Why Convert RGBA to RGB?
Converting RGBA to RGB is useful when you need to work with colors that do not require transparency information. RGB is commonly used in digital fields such as web design, graphic design, and image processing. Stripping the alpha channel simplifies the color representation and is sufficient for scenarios where opacity is not a concern.
How to Convert RGBA to RGB
Converting RGBA to RGB involves blending the RGBA color with a background color, typically assumed to be white, to remove the alpha channel.
- Extract the values for Red (R), Green (G), Blue (B), and Alpha (A) from the RGBA code.
- Example:
rgba(25, 199, 71, 0.5)
gives R = 25, G = 199, B = 71, A = 0.5.
- Example:
- Assume a background color (typically white).
- Background color:
rgba(255, 255, 255, 1)
- Background color:
- Calculate the new alpha value:
- Amix = Afg + Abg × (1 – Afg)
- Example: 0.5 + 1 × (1 – 0.5) = 1
- Calculate the new red, green, and blue values:
- Rmix = (Rfg × Afg + Rbg × Abg × (1 – Afg)) / Amix
- Gmix = (Gfg × Afg + Gbg × Abg × (1 – Afg)) / Amix
- Bmix = (Bfg × Afg + Bbg × Abg × (1 – Afg)) / Amix
- Example Calculation:
- Rmix = (25 × 0.5 + 255 × 1 × (1 – 0.5)) / 1 = 140
- Gmix = (199 × 0.5 + 255 × 1 × (1 – 0.5)) / 1 = 227
- Bmix = (71 × 0.5 + 255 × 1 × (1 – 0.5)) / 1 = 163
- Combine the RGB values.
- Example:
rgb(140, 227, 163)
