How to adjust views by tinting, and desaturating, and more

SwiftUI lets us finely control the way views look by adjusting their brightness, tint, hue, saturation, and much more, all by using various modifiers.

For example, this creates an image view and tints the whole thing red:

Image("paul-hudson")
    .colorMultiply(.red)

You can adjust the saturation of views to any amount, where 0.0 is fully gray and 1.0 is its original color:

Image("paul-hudson")
    .saturation(0.5)

You can even dynamically adjust the contrast of a view by using the contrast() modifier. A value of 0.0 yields no contrast (a flat gray image), 1.0 gives you the original image, and everything above 1.0 adds contrast.

So, this will reduce the image contrast to 50%:

Image("paul-hudson")
    .contrast(0.5)
