We're seeing in certain instances in IE only that when using the HTML editor's color picker, it will give an error that the color code is invalid even when its not. Again, this only happens in certain instances, which seems to be when you select an entire block of text (ctrl+a). I am providing a example of HTML code where this is happening. Using color code 8CD73C as an example, follow these steps:
1) select an entire block of text (using ctrl+a)
2) Click the font color drop down next to alphabet "A" or "A" itself.
4) Click on more colors
5) Click on custom color tab
6) Put the hex code (lets take 8CD73C)
7) Click ok
Alerts popup activated:
"Please enter a correct color value"
HTML code:
<table cellspacing="4" cellpadding="4" border="0">
<tbody>
<tr>
<td style="width: 315px; height: 48px" align="center"><font face="verdana"><strong style="font-size: 12pt; color: #ff0000; font-family: Arial">World Diabetes Day Lighting Ceremony</strong></font></td>
</tr>
</tbody>
</table>
Please have a look and let me know some solution.
