Select image folder:Grey, White or Black.

Navigate different colors from the color popup menu, or by pressing up/down arrows. Click 'Apply' to see changes after adjusting colors.

To adjust multiple items hue at the same time, click and drag 'Hue Multi' control. To set all colors to same hue, hold down the shift key while adjusting 'Hue Multi'.  'Saturation Multi' adjusts saturation of colors and 'Brightness Multi' adjusts brightness. The 'Brightness Multi' is less useful than than the two previous. As colors can go out of bounds and become truncated when using the 'Multi' sliders, it may be necessary to click 'Defaults' to restore default colors or to adjust each color separately.

The images can be colorized. Unlike the  other color adjustments, this processes and saves the image files to a new image set folder for faster loading of images.

If you wish to colorize, first select image set 'Inverted' (as white is usually better for colorization), then adjust the last color named 'Colorize', then click 'Colorize Images'.
