Color Picker does not work for me on Apple devices, this is the html code
<input type="color" class="btn btn-format btn-default attcolor btn-xs" value="#000000">
I do not understand since it works on all devices. In Google I did not get anything referring.
Safari does not recognize certain properties of the inputs, such as "date" for example. This is also the case of "color"; What I can suggest is to use some external plugin like this link
It's as simple as this
<script src="jscolor.js"></script>
Color: <input class="jscolor" value="ab2567">
I hope you serve
