Add Opacity to an Existing Color (by Chris Coyier)
Applying opacity to an existing colour value is a pretty common design requirement, and here Chris presents five ways to achieve it.
Accessible Color Generator
There are many colour contrast checking tools but I like this one from Erik Kennedy (of Learn UI Design) a lot. It features an intuitive UI using simple, human language that mirrors the task I’m there to achieve, and it’s great that if your target colour doesn’t have sufficient contrast to meet accessibility guidelines it will intelligently suggest alternatives that do.
Robb Owen - Independent Creative Developer
Definite “personal website goals” here in Robb’s beautiful online portfolio and blog.
From interaction design to scaleable design systems, single-page apps to something more experimental with WebGL. I help awesome people to build ambitious yet accessible web projects - the wilder, the better.
Here’s a beautiful, magazine style website design for digital publication Bustle. The typography, use of whitespace, responsive layout, menu pattern, colour palette and imagery are all on point!
Are My Colours Accessible?
Colour contrast and the use of colour is extremely important for certain groups of people with varying levels of visional impairment. Building upon the excellent Colorable, I wanted more context around the result. When you share the outcome with your colleagues, all the results, rules and what you’re aiming for, is easily understandable for when you have those awkward conversations with designers and marketers. Accessibility doesn’t have to be ugly.
Who Can Use
It's a tool that brings attention and understanding to how color contrast can affect different people with visual impairments.
Colors – a nicer color palette for the web
Skinning your prototypes just got easier - colors.css is a collection of skin classes to use while prototyping in the browser.
Katherine Kato’s personal website
Some simple but inspiring work here from Seattle-based web developer Katherine Kato. I really like the use of space, the typography, the colour palette and the use of CSS grid for layout.
A handy tool for identifying colours – provided in numerous different CSS-ready formats – and creating a complimentary colour palette from an image you upload or provide as a URL.
