If you don't want to change the color of the icon, framework would choose the right one (dark or light) based on the theme of your actionbar, so for an actionbar with light background, it will choose a darker icon and vice versa; here is a sample app with two different themes, Theme.AppCompat.Light and Theme.AppCompat, respectively (everything else is identical):

As you can see, the appropriate one is selected automatically. If you want to use a different color based on your branding requirements, the easiest would be to add the following images to your project (with usual resolutions under mdpi, hdpi, ..):

• mr_ic_media_route_disabled_holo_dark.png
• mr_ic_media_route_off_holo_dark.png
• mr_ic_media_route_on_0_holo_dark.png
• mr_ic_media_route_on_1_holo_dark.png
• mr_ic_media_route_on_2_holo_dark.png

(if you are using a light actionbar theme, replace "dark" with "light"). Take a look at the assets at Google Cast > Sample Apps (section Cast Icons) to get a feel for what these images are and build your own ones based on those.
