I used to choose the "colorize" option and automatically the image would tirn blue/greenish.
When I last updated GIMP to its latest version, the colorize button no longer works. The same is happening for the HUE options. On the toolbox appears the message:
This tool has no options
Is there another way to get the colorizing effect to an image?
You're looking at the wrong place, "This tool has no options" on the toolbox is normal, it is always there, even when the tool is successfully opened. When the Colorize settings window does not open, you should look at the status bar at the bottom of the window. It is easy to miss since when you move the mouse over the menu, hints are flickering there, so you don't notice when it has changed to something important, and then the message disappears in 7 seconds. The error looks like this:
Here I was trying to run it on an opened GIF file. Since in GIF colors are stored in indexed format, I had to switch the mode from Indexed to RGB (Image - Mode - RGB) to be able to use the tool.
