I don't know it's appropriate to suggest things in this group but I'll give it a shot.
About the Color class' first parameter, it could be either a string or an array. It can be a string of a hex html value, "#ff0000" for example. It can also be an array of the rgb or rgba values: [r, g, b, a]. These are all good but might I suggest a number value as well? Sense javascript has a hex based number syntax you could write 0xff0000 and javascript will recognize this as 16711680. This would be a great feature to the Color class. What do you think?
