Those are HEX values. Since there are exactly 16,777,216 possible hex color code combinations, no one has bothered to name them all. Feel free to start though. :winking_face: I think 64 of them have been named, so that’s a good start.
The names of the colors in the attachment that @Rachel_Passmore shared match the names of the colors in the Custom Apps SDK that @Bill.French linked to. The Custom Apps SDK also provides the getRgbForColor or getHexForColor functions to get the numeric values.
I find it interesting that there are 5 flavors of each the ten color in the image and in the Custom Apps SDK. However, I see only 4 flavors of each of the ten colors when using the user interface.
