# Appearance of a slider

I just observed that in Mathematica 10.3 for Windows the appearance of a slider has been changed. The slider is now blue, black when the mouse is over the slider and gray when the slider is dragged. For me, this blue is too striking, so I would like to change it. In the options of Slider I see that there must be a DefaultBaseStyle for a Slider, but I was unable to find the corresponding style definitions. Is there a way to find and adapt these definitions, e.g. with CurrentValue?

• hmm, I don't see on Win 7 V 10.3.1 what you see. p.s. controllers definitions are somewhere in text resources as Graphics.

• @Kuba. I see this on two computers, each running Windows 10, Mathematica version 10.3.1. On one of them I installed 10.3.1 only two days ago. Feb 13 '16 at 9:10
• Would you please include screen captures so we can see what you're talking about? Feb 13 '16 at 9:43
• Since Kuba is running Windows 7 and hasn't noticed anything, this probably has something to do with Windows 10 as well. Have you tried changing OS style settings to see how they affect this? Feb 13 '16 at 9:49
• A quick search for "Windows 10 slider" leads me to believe that blue is the new style in that version of Windows: cdn.pureinfotech.com/wp-content/uploads/2015/08/… Feb 13 '16 at 9:51

Simply use the wrapper Style[ expr , ControlsRendering -> "Generic" ] or as has been stated in the comments use the option BaseStyle:
Style[

• @grw, this may be useful in some cases where Manipulate should not be wrapped: Manipulate[Null, Style[Control[{{a, 1}, 1, 10, 1}], ControlsRendering -> "Generic"]] Feb 14 '16 at 12:04
