If you are a Designer like me you really have to know your colors. If you don't have them stored in Sketch and you need to know an official Material Design color for a project you'll end losing some time on Google to check it out – well, no more!
Instead of googling them around I created Tint UI to be the source of truth for branding colors and palettes. It was born from a personal need to check those forgetful hexadecimal color codes and quickly copy & paste them to your designs.
That said, I was the founder, designer, coder and one of the +10.000 users that visited tintui.com in the first month. The project had an overwhelming reception and was featured in popular websites like DesignerNews, WebDevTools and Tympanus.
Not only it had a great number of visits but they would also return: 1 in every 3 users would come back in a 30-days time range. I ended up selling the project in early 2017 with 11 color palettes, over 4.000 visits/month and 46% of bounce rate.
When I was sketching the layout for this page I realised that it needed to be very simple because the colors already had a big impact.
The top bar displayed a brief guidance for users "Select a color to copy the hexadecimal code" and after a click it would show feedback of which color you copied. Apart from this, the only interaction left was the sidebar on the left to change to a different palette page. Simple!
After the launch I started receiving user requests, one of them being a switch to show/hide the hexadecimal codes on top of the respective color. The progress of the tool can be seen below together with some Twitter reactions.
3 years after creation, I sold this tool and it's no longer under my management. The design and content weren't modified so you can still play with it and use the 11 color palettes available.
