Google Maps Colorizr
The Styled Maps feature, released in the Google Maps API last year, has proved really popular. It allows map designers to alter the look of Google Maps to match the design of their websites or to emphasise particular map features.
Google's Styled Map Wizard is a great tool for experimenting with and perfecting a style for your Google Map. However the Styled Map function and the Map Wizard both use HSL colors rather than HEX RGB colors, which may be confusing to some users.
The advertising agency stadt.werk has created a new wizard that lets you design your map style in the more familiar HEX RGB colors. The Google Map Colorizr conveniently transfers your HEX RGB colors to the HSL colors used by Google Maps and allows you to cut and paste the code of your finished map style.
The Google Map Colorizr even has a dynamic URL. So if you want to ask someone's opinion about a particluar map style you can send them a link.
