The picture is much too small to see. You should invest in a 30x - 60x scope or jewelers loupe to see the trichome colours. I have a 30x scope and at timees it is difficult to see the colours.
You bud stiill looks rather immature at this stage, im guessing you have minimum 3 weeks left.
Unless you have a macro setting on your camera, it is impossible to gauge it using a camera. As is why I suggested the scope or loupe. From the picture perspective they will always all look milky/cloudy. I wish it was as easy as that lol
