For example, it suggests that it would be better to have black heatsinks and that they are only bright colors for aesthetic purposes. This is definitley not true. Heat radiating-wise, the color does not matter. Emissivity (the property describing how well a material radiates heat) is not directly tied to color. In this case, emissivity will likely be constant with any color because the colors will only be applied via anodizing and different color anodized coatings are almost the same materials.

You may get increased emissivity using an organic paint, but that would hurt you more than it would help. The article fails to mention that the primary mode of cooling for a heatsink for an RC car is through conduction to the air around it, not through radiation. An organic paint would do much more damage by reducing this conduction (metals conduct very well, as you know) than it would help by increasing emissivity.
you may be right about the colors but remember this article is about rc cars. and noone in their right mind would paint their heatsinks. absolutley no function.
