Colours

"The palette should be limited to that of the web site, i.e., white (RGB = 255, 255, 255), a light blue (RGB = 66, 168, 237), darkBlue (RGB = 0, 102, 153), and orange (RGB = 204, 102, 0). Transparent versions of these colours at various levels of opacity are allowed. The actual colors of the design should be white, yellow and black."

this is very confusing to me, are we supposed to be using white, light blue, dark blue and orange, or white yellow and black??
