This is nice, and works really nice for her use case!
Two things to note when thinking about color schemes:
(1) dr. Cynthia Brewer spent way too much time developing the color scheme for maps with information and similar inforgraphics. I can't find the document at this time, but was a lecture long explanation about how she got them.
(2) designers often use "sacred geometry" bullshit like "golden ratio", PI, Phi, and such to explain their thought process. The most common way to create a color palette is to use opposite colors, "triads" and "tetrads". All of this is based on color wheel in HSL/HSV. Which is almost as bad at describing relation between colors as RGB. [2]
PS. my pet peeve for a long time was trying to understand why most color quantization algorithms were relying on finding the distance between RGB colors in 3D space (by mapping RGB components to XYZ coordinates) while it's obviously a terrible way to reason about color relationship.
PPS. a random dude with a similar interest but way more dedication (re)disovered a work by Kubelka and Munk from 1931 describing an algorithm how to properly mix colors and based on that created an incredible graphics program that allows you to paint just like in real life - with oils and watercolors on canvas!

I think it's rather unpleasant for her use-case actually. I rainbow looks quite nice but when used in a dashboard like that... I don't know, the big solid blocks don't look nice to me. I think they're too saturated. They're nicer for the (outlined) squares and lines, not so nice in the donut graph and for the header backgrounds.
