In plain words
Color.review is a web-based tool that helps designers and developers find and test colors for accessibility. It allows users to explore color palettes while checking how they appear to people with color deficiency, ensuring digital work is usable by everyone. The tool addresses the gap between design practice and inclusive design principles.

Find, test & explore accessible colors ✔ 100s of millions of people live with color deficiency, still, we designers & developers often don't make sure that everyone can use our work. I built Color.review to change that.
A modern tool for exploring and finding accessible colors. Make sure that everyone can see your creations.
We experience contrast differently in different colors. Because of how our eyes work, blue text on a white background will be much more easily read than a yellow. When you are designing for humans, in whatever medium, this is something to always keep in mind. Even more importantly, an estimated 217 million people live with a visual impairment. To help make sure that your work can be used and read by as many people as possible, always keep an eye on the relative contrast between your colors. This makes sure that everyone has a chance to view your content, including those with color blindness. For digital work, the WCAG standard has been put together for this purpose and is what this site…from color.review

It's an attempt to create a simple but useful toolbox for common color related tasks and problems. While it's in no way perfect or provides the tools for every use case, it has served me well in the last few months and I hope it will be useful for some of you as well.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
