First open up you image in Photoshop. I’ve chosen the below image and I’m going to focus on changing the colors in the tie and shirt.
Once the picture is open pick the select tool that favours it the best. I’ve chosen the Polygonal Lasso Tool as it’s going to be the quickest and easiest in my opinion. Here’s the selection below.
Next create a new layer in the layers panel. Open up the adjustments panel if you haven’t already and click on Hue/Saturation. Once clicked on the selection will be immediately turned into a layer and ready to work on.
To change the colors move the hue slider first to change the colours. The great thing about it is the two colors in the tie will keep their color balance and the image should keep it’s balance. The further you move the slider the further along the color spectrum you go so you may need to either increase or decrease the saturation underneath. Play around till you get the colors you were looking for. Here’s what I came up with below.
You can always revert back to the original image by deleting or hiding the layer.
In this one I’ve changed the color of his shirt too. By using the color selection tool and raising the fuzziness I managed to select most of the blue before adding the hue.
