Which will heat up faster colored glass, clear glass, or will they heat up equally as fast?

Their the same regardless if there's color or notWhich will heat up faster colored glass, clear glass, or will they heat up equally as fast?
Coloured glass will heat up faster because it absorbs some of the light. For instance, if the glass was coloured red, and you shine white light through it, all the component colours of light except for red are absorbed by the glass, meaning that red light is all that can get through. The rest of the light energy that has been absorbed has to go somewhere, as the laws of conservation of energy state that energy cannot be created or destroyed. This means the absorbed light energy is converted into heat energy which heats up the block. Because the clear glass lets 99.9% of the light through, hardly any light is absorbed and therefore there is little heating in the clear block.Which will heat up faster colored glass, clear glass, or will they heat up equally as fast?
it should be pretty close..but darker glass absorbs more light so it might be a little faster, but not significantly.
