Haxe

`node_modules/@material-ui/core/styles/colorManipulator.d.ts`

```
export type ColorFormat = 'rgb' | 'rgba' | 'hsl' | 'hsla';
export interface ColorObject {
  type: ColorFormat;
  values: [number, number, number] | [number, number, number, number];
}

export function hexToRgb(hex: string): string;
export function rgbToHex(color: string): string;
export function hslToRgb(color: string): string;
export function decomposeColor(color: string): ColorObject;
export function recomposeColor(color: ColorObject): string;
export function getContrastRatio(foreground: string, background: string): number;
export function getLuminance(color: string): number;
export function emphasize(color: string, coefficient?: number): string;
export function fade(color: string, value: number): string;
export function darken(color: string, coefficient?: number): string;
export function lighten(color: string, coefficient?: number): string;
```

This should be added as an extern class to haxe mui

`@:jsRequire('@material-ui/core/styles')` 
I'd just reference this in a `ColorManipulator` class?

You can do things like this
```
import mui.Colors;
import mui.core.styles.ColorManipulator.*;

trace(fade('#DD8800', 0.42));
trace(fade(RGB(255, 255, 0), 0.2));
trace(darken(RGB(255, 255, 0), 0.2));
```

But that's just made me realise something

quoting 'calc()' isn't how i'm meant to use 'calc' xD

You mean that? `maxHeight: 'calc(100% - ${FOOTER_HEIGHT}px)',`

Well that works, do you have issues with it?

I thought I did, but it appears like I missed a css property

I'll see what I can do for string interpolation tonight or this week-end

tomorrow or 2 weeks it's still appreciated 😂

This works, but some times it breaks the language server?

I have to restart the language server or close vscode to get the error to go away

noooo it's something else causing the issue 😭

this is manifesting like the `x` is redefined error
