<h3>Summary</h3> <p>We take it for granted every day, but creating and displaying vivid colors in our digital media is a complicated and often difficult process. There are different ways to represent color, the ways in which they are displayed can cause them to look different, and translating between systems can cause losses of information. To simplify the process of working with color information in code Thomas Mansencal wrote the Colour project. In this episode we discuss his motiviation for creating and sharing his library, how it works to translate and manage color representations, and how it can be used in your projects.</p> <h3>Preface</h3> <ul> <li>Hello and welcome to Podcast.__init__, the podcast about Python and the people who make it great.</li> <li>When you’re ready to launch your next app you’ll need somewhere to deploy it, so check out Linode. With private networking, shared block storage, node balancers, and a 200Gbit network, all controlled by a brand new API you’ve got everything you need to scale up. Go to <a href="https://www.pythonpodcast.com/linode?utm_source=rss&utm_medium=rss">podcastinit.com/linode</a> to get a $20 credit and launch a new server in under a minute.</li> <li>Finding a bug in production is never a fun experience, especially when your users find it first. Airbrake error monitoring ensures that you will always be the first to know so you can deploy a fix before anyone is impacted. With open source agents for Python 2 and 3 it’s easy to get started, and the automatic aggregations, contextual information, and deployment tracking ensure that you don’t waste time pinpointing what went wrong. Go to <a href="https://www.pythonpodcast.com/airbrake?utm_source=rss&utm_medium=rss">podcastinit.com/airbrake</a> today to sign up and get your first 30 days free, and 50% off 3 months of the Startup plan.</li> <li>To get worry-free releases download GoCD, the open source continous delivery server built by Thoughworks. You can use their pipeline modeling and value stream map to build, control and monitor every step from commit to deployment in one place. And with their new Kubernetes integration it’s even easier to deploy and scale your build agents. Go to <a href="https://www.pythonpodcast.com/gocd?utm_source=rss&utm_medium=rss">podcastinit.com/gocd</a> to learn more about their professional support services and enterprise add-ons.</li> <li>Visit the <a href="https://www.pythonpodcast.com?utm_source=rss&utm_medium=rss">site</a> to subscribe to the show, sign up for the newsletter, and read the show notes.

What are the relative benefits of things like RGB, HSV, CMYK, etc.?</li> <li>How is the Colour library architected and how has that evolved over time? <ul> <li>Are there new developments in the area of color theory that need to be periodically incorporated into the library?</li> </ul> </li> <li>What have you found to be some of the most often misunderstood aspects of color?</li> <li>What have been some of the most difficult or frustrating aspects of building, maintaining, and promoting Colour?</li> <li>What are some of the most interesting or unexpected uses of Colour that you have seen?</li> <li>What are your plans for the future of Colour?</li> </ul> <h3>Keep In Touch</h3> <ul> <li><a href="http://www.thomasmansencal.com/about/?utm_source=rss&utm_medium=rss" rel="noopener"
