Feedback on lighting effects

Yellow light: the main focus point of our video is daffodils, which are coloured yellow. so obviously it is important that we find a way to make this lighting effect work. This lighting effect creates a calming effect, which goes well with the song theme. It would be useful to use this in a pub scene if possible. It creates a sort of "glow" which would also make it useful when focusing on each character.
Grey: This does not portray a grey light on the individual, but more gives a spotlight effect. this would be useful when focusing on one character. Generally it can be used to foucs the viewer on one specific thing. things generally appear to shine more. when focusing on the couple this would be a good effect to use.
Red light: this can appear to be more pink than red. However it can also come out, as more like blood red. This can be used to portray feelings of lust and danger, depending on the expressions of the character. Red is often associated with both love and danger. This can give the character a very big shine on their face and thus should be either kept to a minimum or make sure the character is standing in such a way that this is not so obvious.
blue light: this shade of blue gives of a turqoise light. Like the yellow light this can be used to give off a calming effect. It may also be used to give off an eerie effect. this would be a good effect to use in certain shots, such as one with one person moving at a different speed to the rest of the characters.
