Sitting weeks in the European Parliament are split into four areas of activity, each marked with their own colour on the Parliament's calendar, hence the name "colourful weeks".
Red weeks are the monthly plenary sessions in Strasbourg, as well as the six two-day sessions in Brussels.
Pink weeks are when the Parliamentary Committees do their work drafting reports or discussing proposed legislation.
Blue weeks see the political groups get together to discuss which position the group will take on forthcoming debates and legislation.
Turquoise weeks are set aside for work outside of Parliament, such as spending time on constituency work, or taking part in a Parliamentary delegation to a non-EU country.
