Hope this shit helps you out and feel free to tweak it further. The solution I submitted in my PR for work actually wasn't as thorough as the solution I've provided here, so I guess I had some fun optimizing it just for this blog post. Return the resulting RGB colour (Line 35). Get the target RGB values based on the algorithm for alpha compositing or alpha blending (Lines 31-33). Test case of rgb(255,), the RGB values are 255, NaN, undefined.Test case of rgba(36), the RGBA values are 36, undefined, undefined, undefined.CodeīgRgb ? : string } ) => to check this repeating pattern for the RGB values with an optional comma separating them, so the input may not have all values or be in a poor format, therefore not caught by the Regex pattern. Test cases are included below, along with a walkthrough of the code. Here's the solution that I came up with: a helper function to get from a source RGBA colour based on a background color (defaults to white) to the resulting RGB colour.
#RGBA COLOR CONVERTER CODE#
Instead of doing this manually, there has to be a way via code to convert a colour with opacity to the equivalent "solid" colour without opacity, so from a RGBA colour to a RGB colour. Using the colour picker, I can get the equivalent colour: rgba(246,252,250,1) or rgb(246,252,250) without the alpha (opacity). I have a div element with a background colour of teal green at an opacity of 5%: rgba(36,193,144,0.05) There has got to be a function to do that, and there is! Problem Ok, this worked, but what if I didn't want to hard code this result? We had our colour palette as constants in the theme config, so I wanted to be able to pass that colour constant and get the equivalent RGB colour. Frustrated as fuck🤬, I consulted B, who told me that I could just get the equivalent RGB or hex colour without any opacity by using the colour picker in dev tools. Everything was working smoothly, until I noticed my columns kept overlapping the text when scrolling to the left.Ĭhecking the styles, the column had a background colour with opacity.
