Η-Feng

H-Feng is a tool that supports converting Hex color values ​​into RGB and HSL and has a Color memory reversal mini game.
Game rules:
Display phase (5 seconds): The screen displays 3 "Color Name" labels (for example "Red"), but the color and text are inconsistent (for example, the text is green).
Post-memory Challenge: After 5 seconds, all tags disappear and the screen randomly displays a "color name" (such as "red").
You must click out from the color button. In the label that just appeared, the text content is the "color" of the name.
Example:
If the text with "red" appeared before is blue, and the text with "blue" is green...
When the question asks: "Blue", you should click the "Green" button (because the blue text was green at that time).
