Problem with colorify & Hue-Saturation

I have an RGB image (as set by Image-Mode) which is currently black & shades of grey. I want to alter this, in its entirety, so it is blue & shades of blue (a specific colour of blue).

I have tried to vary Hue-Saturation and to colorify (manual says colorify should work on RGB) but although the tools come up on screen, when I adjust the colours in the dialog box my image does not change (I have preview turned on).

The maybe easiest way to do this is to create a new layer atop the Background layer. Fill it entirely with the color of your choice. Then set the lays more to "Color".

Method 1: Create a gradient from your darkest blue to your lightest blue, and use Colors/Map/Gradient map.

Method 2: Add a new layer above the grayscale one, bucket-fill it with your lightest blue, and set it to "multiply" mode.
