Pick A Color is written using angular 2. Colors will persist from visit to visit in local storage.
Any color can be clicked to copy it to the clipboard.
Once a color has opacity hex output will display in rgba when in hex6 or disabled mode. It will convert to hex8 when hex8 mode is selected
At the time of writing this chrome did not support hex8 values and they will not display properly. Switch to hsla or rgba for opacity support.
The color grids might seem confusing at first, but the main color is always in the top left square and other swatches spread out from there in increasing lightness and saturation
