Color Look With An Adjustment Layer
Go to the Layer menu, and then New Adjustment Layer → Hue/Saturation,
and set the blending mode to “Soft Light” and check “Colorize.” Use the
Hue, Saturation and Lightness sliders to control the color: for a cool look,
for example, set the hue at 210, the saturation at 50 and the lightness at 10;
for a warm look, set the hue at 30, the saturation at 30 and the lightness at
5.
