After Approval that TV Channel will follow Roku or Amazonfire Regulations, you will need to provide Graphics and Information.

This image should make it easy for                                                                                                              customers to identify your channel.

Select screenshots that best depict your                                                                                                           channel's user experience and catalog. You can provide up to                                                                                                             six screenshots.

 

Colours

No color should have any R, G or B value higher than 235 or lower than 16.
* Black is not black, and white is not white; instead, use RGB values of 16, 16, 16 for black and 235, 235, 235 for white. It looks terrible on your computer screen, but it looks normal on TV.
* No color should be over-saturated in any one channel, so values in the R, G and B channels should be within 191 of each other. (For example, R 200, G 100, B 50 is good, while R235, G 16, B 16 is not.)

Background color
