Photo Filter Colors In The Swatches Panel

In CS6 or newer, go to the Swatches panel (Window > Swatches) and in the flyout menu (the icon with the down-pointing triangle and four horizontal lines) choose “Photo Filter Colors“. You can then append or replace the current swatches with 20 new color swatches that you can use to apply a photo filter to your image.

For example, to warm your image create a new layer and fill it with any of the warm colors; then change the blending mode to Soft Light and adjust the opacity accordingly. You can fill the layer with any of the other swatches to get different effects.
