Unable to set custom theme

[Milos5611]

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

I want to add some custom colors as primary for theme.

Current Behavior

Updating theme with custom color not possible. New object is updated with new color but theme property not get updated.

Steps to Reproduce (for bugs)

I call createMuiTheme method and pass object

const default_theme_obj = {
    fontFamily: "Roboto, sans-serif",
    palette: {
        primary: "#fff"
    },
};

but when i pass it as theme={default_theme_obj} to MuiThemeProvider nothing happen, it still have default MUI theme colors. This is exacly how it was worked it v0.19.

Context

I expect that theme is updated with new color set as primary.
My app have several different theme depend on user role. When user is on login page default should be applied with color from DEFAULT_THEME object and when user get access he also get theme from DB which is applied to MUI. It was working really well in v0.19 but when i switch MuiProvider is never updated.

Have a closer look at the documentation and the warnings in your console. The theme colors with Material-UI are rich objects containing hues (#xxxxxxx).
