determine, using the graphic processor, a second dominant color in a second data block of the background multimedia frame of the digital multimedia content, the second dominant color being different than the first dominant color, and the first data block and the second data block corresponding to different portions of the background multimedia frame;
determine, using the at least one criteria, a second color that contrasts the second dominant color; and
assemble a set of graphical items received from a user interface generator, the set of graphical items forming the user interface being displayed in relation to at least a portion of the digital multimedia content, the set of graphical items including a first graphical item and a second graphical item, the first color being applied to the first graphical item, and the second color being applied to the second graphical item, the first and second colors being selected so as to be visible in a part of the digital multimedia content where the first and second graphical items are displayed.
8. The system according to claim 7 , wherein the digital multimedia content is provided by a video transport stream comprising I-frame data blocks, and wherein the graphic processor is further configured to extract, from the I-frame data blocks, information associated with the first and second dominant colors in the background multimedia frame.
9. The system according to claim 7 , wherein the digital multimedia content is provided by a camera implemented in smart glasses or a windscreen, and wherein the graphic processor is further configured to extract, from color composition, information associated with the first and second dominant colors.
10. The system according to claim 7 , wherein the first color is determined according to user preferences introduced in an interactive manner when graphical items of the user interface are displayed based on pre-stored settings.
11. The system according to claim 7 , wherein the first color is determined according to a quality of the digital multimedia content represented by the background multimedia frame.
12. The system according to claim 7 , wherein the graphic processor is further configured by the executable instructions to change color of graphical items within a predefined time period by introducing a progressive transition through less dominant colors.
13. A non-transitory computer-readable medium of a server computer having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:
determining, using a graphic processor, a first dominant color in a first data block of a background multimedia frame of digital multimedia content;
determining, using at least one criteria, a first color that contrasts the first dominant color, the at least one criteria including selecting a contrasting color for at least one graphical item of a user interface based on a genre of the digital multimedia content;
