How Agamemnon should tranform designing wise throughout the play???

Costumes:
Tricky if those who don't have a genuine idea of how the play is formed. So we know at the beginning of the play we are given a signal from offstage when "Troy" had fallen. So we begin with the rejoice idea (holy, pure):

Very casual and powerful among this figure. However as the play progresses the power gets to the clothing by consuming it with some sort of dark and rich matter (It could be blood or rags), but it should be gathering enough for when Clytemnestra kills him it represents the rage which is released upon him.


Lights:

The lights during the play are soft focus but becomes more scheming of who is where feel. Example below:

Beginning

The green in this light could reflection of the signal for the soldier which would bring the stage lights up to general showing that Troy has fallen.

Then when the play progesses into the dark a tragedy side it forms into this

Then the murder for lights transforms into the painting

Blackout
What do you guys think?
