The full form of RGB is Red, Green, Blue, Alpha.Īnd the min value of RGB color is 0 and the max value is 255. In CSS RGB Color is specified with the rgb() function, and the syntax is: Not: Hexadecimal color with the alpha channel has extra 2digit for representing transparency or opacity, for that the syntax of HEXA color formate should be: #rrggbbaa, here “aa” represents the opacity of the color, the minimum value of alpha is 00 and max value is ff.

Now let’s write a color code for green and blue: #00ff00 (for green) and #0000ff (for blue) here 00 means no color. If you want to create original red color in hexadecimal formate by following the hex color formate role the color code should: #ff0000 In this system “#” represents that this code is a hexadecimal color code, “rr” represent the color code for red in hexadecimal number and its minimum value is “00” and the maximum value is “ff”, same as “gg” represent color code for the green in hexadecimal and last one “bb” represents the hexadecimal color code for blue color. In Hexadecimal number system, it has 16 alphabet like: 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f and in Hexadecimal color formate has three part like- red, green and blue. Saturation is the value between 0% to 100% 0% means a shade of gray and 100% is the full color. Here Hue is the degree on the color wheel between (0-360), in the color wheel 0deg or 360deg is for red color, 120deg for green, and 240deg is for blue color. The full form of HSL is H: hue, S: saturation, lightness.

Since RGB are based on a 255 scale, I just needed to divide the RGB value by 255 and I get the matrix value for each channel.RGBA to HEXA Color Converter is an online-based free tool to convert RGBA color to HEXA color, without installing any software to your device. It’s not a common problem to have, no one was asking about it on StackOverflow. But what I needed for the mosaic was to reproduce an exact RGB value into the color matrix, and that was tricky. RGBA to feColorMatrixĬolor manipulation with feColorMatrix seems limitless, I could colorise an element any way I wanted.

Una Kravets wrote an excellent list apart article explaining how to use it. This filter is really powerful and allows granular per channel color manipulation, kinda like editing the channels on Photoshop. Every pixel’s color value (represented by an vector) is matrix multiplied to create a new color.
The feColorMatrix is an SVG filter that changes colors based on a transformation matrix.
That also implied changing our CSS blend modes to an SVG filter, in this case the feColorMatrix filter. Mapping an image and building a mosaic following some CSS filters and blend modes took about 3 days to a skilful DOM manipulator like Brian.īut we’ve spent at least a moth iterating on designs details, trying new animations and optimising the performance.ĭuring one of those iterations, and aiming to achieve good performance and smooth animation we’ve tried SVGs instead of HTML images. It was an impressive visualisation that I helped Brian Leatheam create. The presentation ended up dynamically building a picture mosaic of the Red Hat logo out of selfies taken by the audience. This year I’ve been lucky enough to be part of the team building the Red Hat keynote demo at Red Hat Summit.
