Here's why:
* Eye color is determined by genetics: The amount and distribution of melanin in your iris determines your eye color. This is a biological factor you can't change with markup.
* Markup is for digital display: Markup languages only affect how things appear on a computer screen or web page. They don't interact with the physical world.
If you're interested in changing how your eye color appears in photos or videos, you could try these options:
* Photo editing software: Software like Photoshop or GIMP allows you to adjust colors and create the appearance of different eye colors.
* Color contact lenses: These can temporarily change your eye color.
Remember, it's important to be safe and consult with a professional if you're considering using any products or techniques to alter your appearance.
