And from the sound of your dragon, it seems he is of the black dragon line (copper base). These dragons usually have silverish bodies instead of white like the red dragon.
Irid based dragons show irid colors on their whole body and fins. The turquoise or blue-ish dragon may show two colors from different light angles - ssometimes more blueish, sometimes more greenish. The royal blue and steel blue usually only shows one color.
