To make a color-magnitude diagram (CMD) or a color-color diagram, you need to (1) convert any fluxes/flux densities you have to magnitudes; (2) compute colors by taking bluer color minus redder color (e.g., B-V or K-[24]); (3) if a CMD, plot magnitudes on the y-axis, with brighter objects (''smaller'' numbers, so reversing the 'standard' y-axis) on the top; (4) if a CMD, colors should be on the x-axis and increase to the right; if a color-color diagram, colors should be on both axes, increasing to the top and right.

To make a color-magnitude diagram (CMD) or a color-color diagram, you need to (1) convert any fluxes/flux densities you have to magnitudes; (2) compute colors by taking bluer color minus redder color (e.g., B-V or K-[24]); (3) if a CMD, plot magnitudes on the y-axis, with brighter objects (smaller numbers, so reversing the 'standard' y-axis) on the top; (4) if a CMD, colors should be on the x-axis and increase to the right; if a color-color diagram, colors should be on both axes, increasing to the top and right.
