literally no class names anywhere in the components except for the root element

How am I suppose to style this component using CSS if there are no class names that define the UI elements? All I see for the Chrome Picker is the root div has a "chrome-picker" class and the hue bar has a "hue-horizontal" class name, but everything else uses inline styles. How can this component be in production in this state? This is something a junior developer would build.

Start by inspecting the Chrome Picker component and the rendered elements that currently rely on inline styles; the issue identifies only the root `chrome-picker` and hue bar `hue-horizontal` classes. Determine the intended class-name coverage and verify that the component remains correctly styled while its UI elements can be targeted with CSS.
