Hi there:
I have the same mobo, rev 1.2 It is the blue white theme, but the picture shows the red, yellow and green.
I think after the rev. 1.0, the color theme was switched to blue, white to match the rest of Gigabytes
color themes for their other boards.
As Dark Mantis said, only trust the markings on the board, for bios updates and software from Gigabyte.
Don't go by the pictures, as board components are subject to change with time and supply availability.
Hope this answers your questions and/or concerns.
