Is the light temperature slider in Elements 9 reversed?

In Photoshop Elements 9 (I'm not sure about others) the light temperature slider bar is backwards; in nature, the higher the kelvin temperature, the bluer the light. In PSE 9 the higher the kelvin temperature, the more amber the picture becomes. Or is the PSE 9 lighting system not based on kelvin? Anyone else noticing this in their versions?

To compensate for an image shot under a high color temperature, you have to make the image more amber. To compensate for an image shot under a cooler color temperature, you have to make the image more blue.

You are not simulating the color temperature, but correcting for it.

Looking at the the slider some more, your explanation makes sense, but the Kelvin-esque numbers above the slider do not correspond to the light color correction.

I know that the ACR white point slider is well calibrated and does match actual lighting conditions quite well. But I don't know if Elements has an additional color correction that I haven't seen, beyond what is in ACR.

I am doing research on this right now, and it looks like Photoshop is using the Mired light scale to measure and adjust the light color temperature instead of the Kelvin scale. This is fine and works well, but is confusing to the uninitiated. Thank you for your replies.
