Problem

Using IM4 on editing POD chart colour attributes a color picker box does not appears.

Solution

To solve this issue you need to login into IM4 framework on APEX. Go to page 997.

 
You need to change the first line :

<script type="text/javascript" src="/&FRAMEWORK_DIR./jquery/colorpicker/jquery.colorpicker"></script>

To:

<script type="text/javascript" src="/&FRAMEWORK_DIR./jquery/colorpicker/jquery.colorpicker.js"></script>

And color picker will appear on (IM4/admin/POD maintenance/chart attributes):
