Colour variations
Nametags can be in Calming green, Powering green, or white backgrounds. Choose the colour version best suited for the overall colour theme of the video and make sure that the nametags stand out from the background video. Primarily use only one colour theme for all nametag instances per video. Prefer the green versions. If the speakers need to be differentiated from each other in the video (e.g. Fortum people and outside speakers), two colour versions can be used in a video to clearly indicate the different backgrounds of the speakers.
In this case use either of the green versions for Fortum and the white version for other speakers.
