RGB Color changes without masking!
Define the source colors you wish to operate on, you may select multiple colors with a color picker. You can take advantage of RGB, LAB or HSV space to perform color changes even if the image remains in RGB. Simply sample the colors in the area you wish to affect with the built in Color Sampler Tool, and slide the bars to get the color you want to reach, you can adjust the range and limit the extent of modifications. An easy brush mask creates an instant selection and quickly limits the effect. Unlike Photoshop HueSaturationValue changes, the selectivity range will limit the effect to the color you want to change and will keep all the shades for a natural rendering!
