Yes! This is oddly inconsistent between Microsoft products and it makes no sense. With people tend to develop a system of colour-coded highlights: for me, yellow is important but orange is more so. It is frustrating not to be able to use this in Word, but instead jump from yellow to intense, angry red.
It also has the effect of seeming to date MS Word back to when the 16 colours were the standard. The world has moved on, Microsoft!
