Green is not a primary color

Just want to point out that green is NOT a primary color.
When mixing colors, blue + yellow == green.
Yellow is a primary color.
I’m kind of suprised that no one in the editing staff picked up on this.
I think this goes back to the fact that the television (and now computer monitors) use red, blue and green. The display of yellow is actually the subtraction of blue from green.
I would guess that there are more engineers writing programs than artists. I could be wrong on this point.
Many engineers (and programmers) have some historic knowledge of television and how it represents color from their training. That knowledge is more recent than the art classes they may have taken as children where they learned the primary colors.
In closing let me say that the fact that green is not a primary color should not detract from the fine work that Venkat has put into this book. The examples that use green as a primary color are good examples of Scala programming. My hope is that the examples might be corrected and replace green with yellow as a primary color.
Thank you for your fine work.
