I would extract drawables and xml from Android source code and change its color to red. Here is example how I completed this for mdpi drawables:
Custom red_scrubber_control.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/red_scrubber_control_disabled_holo" android:state_enabled="false"/>
<item android:drawable="@drawable/red_scrubber_control_pressed_holo" android:state_pressed="true"/>
<item android:drawable="@drawable/red_scrubber_control_focused_holo" android:state_selected="true"/>
<item android:drawable="@drawable/red_scrubber_control_normal_holo"/>
</selector>Custom: red_scrubber_progress.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@android:id/background"
android:drawable="@drawable/red_scrubber_track_holo_light"/>
<item android:id="@android:id/secondaryProgress">
<scale
android:drawable="@drawable/red_scrubber_secondary_holo"
android:scaleWidth="100%" />
</item>
<item android:id="@android:id/progress">
<scale
android:drawable="@drawable/red_scrubber_primary_holo"
android:scaleWidth="100%" />
</item>
</layer-list>Then copy required drawables from Android source code, I took them here: https://github.com/android/platform_frameworks_base/tree/ics-factoryrom-2-release/core/res/res It is good to copy these drawables for each hdpi, mdpi, xhdpi. For example I use only mdpi:
Then using Photoshop change color from blue to red:
red_scrubber_control_disabled_holo.png: 
red_scrubber_control_focused_holo.png: 
red_scrubber_control_normal_holo.png: 
red_scrubber_control_pressed_holo.png: 
red_scrubber_primary_holo.9.png: 
red_scrubber_secondary_holo.9.png: 
red_scrubber_track_holo_light.9.png: 
Add SeekBar to layout:
<SeekBar
android:id="@+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:progressDrawable="@drawable/red_scrubber_progress"
android:thumb="@drawable/red_scrubber_control" />Result:
Edited:
Here is nice resource Android Holo Colors Generator that will help to create elements with different colors much faster. Just select color and element and it will create required drawable for xhdpi, hdpi and mdpi.
