How to use colorisation with precision (e.g. with hex code) in Photoshop Elements 12?
I have Photoshop Elements 12. I have an image that I want to colorise to match a specific RGB/hex value, but in Photoshop, Enhance > Adjust Color > Adjust Hue/Saturation leads me to a pop-up box with sliders for hue, saturation and lightness, as shown below. It appears that it's only possible to judge by eye, which is not what I want.

Following the 'Help' link takes me here but none of that seems to address my problem.
Am I stuck with just trying to use the sliders and judging the resulting colour by eye?
