i feel It is testing by using bitmap checkpoint

Here we have to identify which test have to do first, 
through Image and Bitmap check points we can test 
applications .....

May be QTP Provides the Page Checkpoint I mean By using 
this we check the All the contents of a Web page

Correct me If Iam wrong

background color you can test with bitmap checkpoints, but 
moving image you gotta go for multimedia addin... 

let me know if you need details..

e4ven i dont know

i am not sure about testing the back groung color but
the code below
Dim ctrlWebEl, objWebEl 
Set ctrlWebEl =Browser("Google").Page("Google").Link("Go to 
Google.com")
Set objWebEl = ctrlWebEl.Object 

sColor = objWebEl.currentStyle.color 
sBackgrColor = objWebEl.currentStyle.backgroundColor
sFontSize = objWebEl.currentStyle.fontSize 
sFontStyle = objWebEl.currentStyle.fontStyle
sFontFamily = objWebEl.currentStyle.fontFamily
sFontWeight = objWebEl.currentStyle.fontWeight
msgbox
(sColor&"        "&sBackgrColor&"        "&sFontSize&"      
  "&sFontStyle&"        "&sFontFamily&"        "&sFontWeight
)

helps us to get the color of a link or a webelement 

we can do this using standard check point as well 
not sure if this is the answer for ur questions
