- Color History: Keep a history of selected colors
- Copy to Clipboard: Add buttons to copy RGB/HEX values
- Color Palette: Save selected colors to a palette

// Example enhancement for image upload
document.getElementById('imageUpload').addEventListener('change', function(e) {
const file = e.target.files[0];
if (file) {
const reader = new FileReader();
reader.onload = function(event) {
const img = new Image();
img.onload = function() {
// Draw uploaded image on canvas
ctx.drawImage(img, 0, 0, canvas.width, canvas.height);
};
img.src = event.target.result;
};
reader.readAsDataURL(file);
}
});This enhancement would allow users to analyze colors in their own images.
