Changing the colors in a photo to a specific new color can be achieved through various image editing tools and software. One effective method is to use the Color Replace tool in image editing programs like Pixlr or Adobe Photoshop.
In Pixlr, you can access the Color Replace tool by clicking on the Brush icon in the toolbar and selecting Color Replace Brush from the dropdown menu. This allows you to select the color you want to replace and the new color you wish to apply. You can also adjust the threshold to change similar shades of the selected color. Similarly, in Pixlr X, you can find the Replace Color tool under the Retouch category in the Tools section. Online tools like JPG Tools and Image Tools also offer color replacement features, where you can simply specify the new desired color and click on the area you want to change.
