I don't really mean that the color was changed from the first original photograph, but that they color balance is not natural. I really doubt that the colors shown in that image even if it's the same as in the book, truly represent the colors of the flower and it's surroundings. Not necessarily meaning that somebody changed colors on purpose, but when a slide gets scanned and then an image is inked and pressed, it doesn't necessarily look what the original is, especially if the photos do get over-saturated a bit to make images pop more to get more book sales. Look at lots of color orchid catalogs, the colors have been extremely over-saturated and over-tinted in the color direction the vendor wants you to see... if somone was trying to sell you a 'new' blue phal then often the color of that picture is leaning heavily more blue than is natural. Also can be from aging of the dyes on the printed page, or just a bad color reproduction from the dyes by the printer.
