Was the colour of the bedroom curtains as seen by Matt a clue?

The curtains are blue & white, not purple & white. What do you get if you mix blue with amber & white with amber?

It wasn't mixing paint but light?

I don't know to be honest.

There's the possibility of an an orangey light seen through a blue and white pigment material.

It's also possible that Matt recalled some light, but the memory got confused as to the hues if they were different from those in his own flat.

If the shutters were down the curtains would not have had a green & yellow hue.  He could see the curtains from the doorway to the bedroom where he stood to observe.

It is my understanding that the shutters could be down at two levels, misty.

1)  They could be down but with the slats not fully closed, so exposing multiple small slots which let in light throwing a little light into the room, OR

2)  They could be hard down, with all the slots closed off, so no light came thru.

Difficult for us to know if the shutters were in position 1) or whether they were actually  lifted when Matt did his 9.30 check.

Because so little street light would have penetrated the heads of the trees (as it was then) surrounding block 5,  I tend to favour that the shutters were actually lifted at Matts visit.

Seems Madeleine had actually been abducted by 9.30, IMO

You might wish to check Matthew's statement in Portuguese.  From memory, Pathfinder has raised the point that the bedroom Matthew was talking about having light from outside was the parents' bedroom, not the children's.

That's the first I have heard of it being the parents bedroom that Matt was talking about.  where did she get that info from?

I feel sure he was talking about the childrens bedroom.  Pls correct me if I am wrong.

In one of his statements he talks about the shutters being up in the parents bedroom as well.

Excellent detective work misty!!   I would think that even if the curtains were a light purple you would still get a green hue.

Could anyone run a test please?

I am gobsmacked that everybody didn't know that as far as paints are concerned,

Yellow + blue = Green

But then I was an Art teacher,.


Using light, I am not absolutely sure altho on the rainbow, which is light rays deflected and parting on water, it is also true. 

Blue as it mixes with yellow becomes various shades of Green. 

The more orangey the light becomes, the more olive-green the mix is.

I fear low pressure sodium lamps may be in short supply for such a test.
An orange filter will not do as it will still let light of other wavelengths through.
You would also need material from the same batch and different cloth dyes may well give different results

I'm tending to believe he was right for how did the wind blow into the apartment unless there was somewhere for it to go.   Trouble is no one else noted these shutters up.

Who would have shut these shutters and not say anything?

It went to an area of low pressure!

Buildings are not sealed in the sense they become airtight.

The second link confirms what I was saying.
..... the wind blows into the apartment if there was somewhere for it to go. ....

Natural ventilation is achieved by infiltration and/ or by allowing air to flow in and out of the building by opening windows and doors. 

Note:  "in and out of the building" not just in one direction
