myFiles.load(x coordinate, y coordinate, image-x-size, image-y-size, fname[, buffer-size-multiplier, invert colour]);
x coordinate, y coordinate = screen coordinates
image-x-size, image-y-size = size of image
fname = image filename
buffer-size-multiplier = 1 by default (buffer = image-x-sizebuffer-size-multiplier2) (try 2, 4, 6, 8 )
invert colour = 0 by default (try 1 if colour wrong)
You have downloaded UTFT_SdRaw?
All I can suggest if you think colour is not as it should be, is change invert colour to 1.

Edit: Download and rename SK400500.raw.txt to SK400500.raw put it on your sd-card not in a folder. Run that sketch.
Be aware that SK400500.raw is already inverted colour compared to the output from Henning's converter! This should CLEARLY demonstrate the buffer and invert colour features.
