When editing photos within the Instagram app, which filter would best be used to intensify the colours of an image?

Saturation directly controls the intensity and vividness of colors in an image. Increasing saturation makes colors appear richer and more vibrant, while decreasing it makes them duller or even grayscale. Contrast adjusts the difference between the lightest and darkest areas of an image, affecting overall depth but not color intensity directly. Highlights brightens or darkens only the brightest parts of an image. Structure enhances details and textures, making the image appear sharper, but doesn't specifically intensify colors. Brightness adjusts the overall lightness or darkness of an image.
