I have some React code implementing some Material-UI components and a theme. According to this "light: will be calculated from palette.primary.main". I have provided a specific hex color for main, and it works, as does the secondary color. However, theme.palette.primary.light doesn't provide a lighter color, just provides a lighter gray color. I output the theme JSON value near the bottom of the code below and it all looks good - there's a value of rgb(73, 100, 169) which looks like a legit light value of the theme.palette.primary.main value. But long story short, the useTheme() returns a legit theme, but the second button value of theme.palette.primary.light looks like a generic-ish gray color. So any idea why the light value isn't making it to the component?
THANKS!
