Random Color Picker In jQuery

A user-friendly, jQuery based color picker for generating random colors that you can easily copy the HEX color code to the clipboard with a single click.

How to use it:

1. Add fallback colors together with Refresh/Gradient Buttons and Copied info box to the color picker.

<div class="colors-container">
  <div class="color">
    <div class="color-hex">#000000</div>
  </div>
  <div class="color">
    <div class="color-hex">#000000</div>
  </div>
  <div class="color">
    <div class="color-hex">#000000</div>
  </div>
  <div class="color">
    <div class="color-hex">#000000</div>
  </div>
  <button class="refresh">Refresh Color</button>
  <button class="generate-gradient">Generate Gradient</button>
  <div class="copied">Copied!</div>
</div>

2. The required CSS styles for the color picker.

.colors-container{
  width: 100%;
  min-height: 100vh;
  display: flex;
  flex-wrap: wrap;
}

.color{
  flex: 25%;
  min-height: auto;
  transition: .4s linear;
  cursor: pointer;
  position: relative;
}

.color:hover{
  filter: brightness(80%);
}

.color-hex{
  position: absolute;
  bottom: 10%;
  width: 100%;
  text-align: center;
  color: #fff;
  font-size: 24px;
  letter-spacing: 2px;
}

.refresh{
  position: fixed;
  top: 20px;
  right: 20px;
  width: 50px;
  height: 50px;
  border: none;
  border-radius: 50%;
  font-size: 18px;
  color: #fff;
  background-color: #000;
  outline: none;
  cursor: pointer;
  transition: .4s linear;
}

.refresh:hover{
  transform: rotate(180deg);
}

.copied{
  position: fixed;
  bottom: 20px;
  left: 20px;
  color: #fff;
  background-color: black;
  border-radius: 50px;
  padding: 15px 40px;
  min-width: 340px;
  text-align: center;
  display: none;
}

@media screen and (max-width:800px){
  .color{
    flex: 100%;
  }
}

3. Load the jQuery library in the document.

<script src="/path/to/cdn/jquery.min.js"></script>

4. The main JavaScript function to generate colors and gradients.

var colorNames = {
    "#000000": "Black",
    "#ffffff": "White",
    // Add more color mappings as needed
};

function generateGradient() {
    var color1 = "#" + Math.random().toString(16).substr(2,6);
    var color2 = "#" + Math.random().toString(16).substr(2,6);
    
    $('.color').each(function(index){
        var gradientColor = interpolateColor(color1, color2, index / 3); // 3 is the number of color blocks
        
        $(this).css('background-color',gradientColor);
        $(this).children(".color-hex").text(gradientColor);
        $(this).children(".color-name").text(colorNames[gradientColor.toUpperCase()] || "Unknown");
    });
}

function interpolateColor(color1, color2, factor) {
    if (color1.length !== 7 || color2.length !== 7) return null; // Invalid color format
    var result = "#";
    for (var i = 1; i <= 6; i += 2) {
        var c1 = parseInt(color1.substr(i, 2), 16);
        var c2 = parseInt(color2.substr(i, 2), 16);
        var interpolated = Math.round(c1 + factor * (c2 - c1));
        result += ("0" + interpolated.toString(16)).slice(-2);
    }
    return result;
}

$('.refresh').click(function(){
    $('.color').each(function(){
        var rColor = "#" + Math.random().toString(16).substr(2,6);
        $(this).css('background-color',rColor);
        $(this).children(".color-hex").text(rColor);
        $(this).children(".color-name").text(colorNames[rColor.toUpperCase()] || "Unknown");
    });
}).trigger('click');

$('.generate-gradient').click(function(){
    generateGradient();
});

5. The main JavaScript to copy the selected color to the clipboard.

$('.color').click(function(){
    var input = $('<input>');
    var color = $(this).children(".color-hex").text();
    $('body').append(input);
    input.val(color).select();
    document.execCommand('copy');
    input.remove();
    $('.copied').fadeIn().delay(2000).fadeOut(); 
});
