+## Colors
+
+Svg.js has a dedicated color module handling different types of colors. Accepted values are:
+
+- hex string; three based (e.g. #f06) or six based (e.g. #ff0066)
+- rgb string; e.g. rgb(255, 0, 102)
+- hsb string; e.g. hsb(336, 100, 100)
+- rgb object; e.g. { r: 255, g: 0, b: 102 }
+- hsb object; e.g. { r: 336, g: 100, b: 100 }
+
+Note that when working with objects is important to provide all three values every time.
