Eye shadow should ideally match which part of the makeup?

Eye shadow should ideally complement the color of the iris. The reason for this is that when eye shadow is chosen based on the shade of the eyes, it enhances their natural beauty and draws attention to them. This practice helps create a harmonious and cohesive look, allowing the eyes to stand out as a central feature of the face.

Different colors can be used to make the eyes pop or to create a desired emotional effect. For instance, for blue eyes, warmer tones like copper and peach can be striking, while purples and mauves can make green eyes appear more vivid. By selecting eye shadow based on the iris color, makeup can truly enhance the wearer’s overall appearance.

While matching eye shadow with skin tone or other facial features can lead to aesthetically pleasing results, the primary focus of eye shadow is to accentuate the eyes themselves. Each choice in the context aims at achieving an appealing overall look, but the specific target for eye shadow is the iris's color.
