Reaction Post to Throne of Blood

Well I can now one up my friends and family when it comes to film. I know for a fact that none of them have watched a 1950's, black and white, Japanese film. I'll be honest, Throne of Blood is nothing what I expected. I'll admit, it was a bit difficult going from Goold's Macbeth where everything (except the time period) is very similar to the original text, to Kurosawa's adaptation that is much different in terms of the original text. Obviously the language and culture are completely different so I suppose it is understandable as to why it is much different than Goold's Macbeth.
One scene I found particularly interesting was the scene where Washizu is sitting down talking to Lady Washizu. In Goold's Macbeth I didn't feel as strongly emotionally when Macbeth and Lady Macbeth were discussing killing the king. However, in Kurosawa's adaptation I felt almost sick to my stomach while they were talking, especially when during Lady Washizu's line when she said, "Children kill their parents for less. This is a wicked world. To save yourself you often must first kill." All throughout this conversation Lady Washizu calmly sits in the corner while she says all of these horrible things which, in my opinion, make her even more sinister seeming.
Another scene that was much more emotionally charged for me in this adaptation was when Washizu finds out that Lady Washizu has committed suicide. Several women are knelt down on their knees weeping for the now dead queen while Washizu calmly rides on by as if nothing ever happened.
It's not so much a question as it is a overwhelming curiosity but throughout the film I was constantly wondering what the film might have looked like if it was filmed a few years later in color? From the few pictures I've seen, Japan looks very beautiful. Even though it is in black and white, I feel as though Kurosawa did a wonderful job with the costumes in making them look very traditional and extravagant. I found this to be especially true for Lady Washizu's costumes but also Washizu's as well.
