Hello Shengjie,

Could you tell me more exactly of what part you would like to change the color? The bluish gray background or else?

Hi Noriko

       I take another look. The snapshot is come from 'RoyalLight' theme. But 'Office2013' is closer what I want.

1. I need the foreground color of disable item of 'RoyalLight' theme.

2. I need the background be a solid color

If you have other question, please let me know. Thanks

It looks I use following code to change disable text color. 

<SolidColorBrush x:Key="{x:Static igRibbon:RibbonBrushKeys.GrayTextBrushKey}" Color="#FF7E8A98" />

Thank you for sharing the information. I guess you've already solved the issues except the "2. I need the background be a solid color".

As to the "2. I need the background be a solid color", it's already solid because, whether you use RoyalLight or Office2013, that part is filled with the color provided by the ApplicationAccentColor property. As you already says, you give "#B3C4D8" to it. So it is already solid.

Could you double-check?

But the display is not solid, obviously it is gradient color from the top to bottom. That's why I ask your help. Could you check it again?

Hello Shengjie,

Thank you for the reply. Then, I guess all of your issues are solved.

If you need further assistance on this matter, please let me know.

Hi Noriko,

         You are right. I try to change the code in Samples Browser and get same result. It looks it is just a visual psychological difference. Thanks

Here is the screenshot you shared with me. I copied the upper part and pasted it to the bottom. As you can see, the color is the same, not gradient. Could you tell me which part is gradient?
