![]() ![]() In our case, we aim to pass AA level success criteria for color contrast in WCAG standards. So before we jump into color creation, we should think about 3 important objectives that we would like to achieve. I believe that the strong system (of any kind) is based on the process which comes with a great plan. Simply put, with HSLuv we can control the contrast while keeping the look and feel of the colors same across our whole palette. Not only that the HSL range varies so much in uniformity while being based on the same lightness number as HSLuv, but when we look at the grayscale range on right, it’s obvious that HSL lacks heavily in contrast too. In the picture below we can see the obvious difference in the perceptual uniformity of HSLuv colors in the first column and HSL in the second one. The good news is that in 2012 Alexei Boronine created the HSLuv model which solves the issues by combining the best of both worlds - it uses the lightness component of CIELUV and pairs it with hue and saturation, making it into a tool with values that are easily understandable and useful. Besides the lightness component, U and V represent chromaticity coordinates of the color.īut CIELUV is again not very intuitive to use, because of the input values. Luckily for us, in 1976 we got a CIELUV color model that was created to fix that through a lightness component matching how a human eye perceives colors. But HSL only simplifies the process of work with that color model still ignoring the overall complexity of the color appearance. It shows colors on a simple and easy to visualize 360-degree color wheel (technically a cylinder because of the lightness component). You are probably familiar with the HSL color model which solves the lack of intuitiveness in RGB by changing the values into something more understandable: Hue, Saturation, and Lightness. Not only that RGB model doesn’t reflect the true color space, but it’s also not intuitive for using at all - the three coordinates that create a color based on a mix of Red, Green, and Blue don’t make it that clear what we are actually doing. Unfortunately, this is the biggest drawback of RGB. Ideally, our tools are intuitive and simple, making our work efficient with room for seamless tweaking, allowing us to understand the connections between the values we put in and we get out. While we don’t need to master theory on color, having a sense of the most used color models and their relationships to our workflows will help us to understand why HSLuv shines among others. A brief look into color modelsįirst, we have to dig a bit into the usual color models and how we work with them. Actually it’s quite surprising how much it’s still ignored. It seems that while we can find endless sources of articles on color theories, color wheels, and color pairing, the knowledge that shows anything related to HSLuv is pretty scarce, especially on the design side. But the road to understanding its full potential was not that easy. HSLuv color model solves that, at least more than anything else available to my knowledge. ![]() So how we can make great experiences if our color system is falling apart? HSLuv, nice to meet you And if they do, they have different contrast, so they are not similar at all. And often we hit that wall of unknown - we get angry that our colors are technically similar, but they don’t look that way. We keep working with tools that do not give us anything better. We work with digital devices by looking at our screens through human eyes. You can tap the white balance button repeatedly to loop through available modes until you find the one that is best for your setting.I think we all agree that colors are simply hard. You may also need to enable the white balance feature to improve color accuracy whenever you are indoors or under direct sunlight. To turn the flash on or off, click on the light button at the top-right corner. ![]() In a low or poorly-lit environment, turn on your mobile phone flash. Many raised bars mean that the captured color is perfect for your color type. The bar’s height grows with the likeness between the captured color and the color in the palette. Each bar signifies an individual color in the active palette. There is a row of colorful bars at the bottom of the screen. Tap the square swatch to open the captured color in the Fabric Preview Page. You can switch between the two modes by clicking the lock icon on the square swatch. Overlay mode allows you to freeze the color of the square swatch and see how the captured color (star rays) and the chosen color (square swatch) work together. ![]()
