Not able to use black in COLOR_PALETTE

[shaun-visser]

Love the work!
Setting canvas to a white background - I'm not able to set black in the color pallet e.g.
useEffect(() => {
webGLFluidEnhanced.simulation(canvasRef.current!, {
SIM_RESOLUTION: 128, // Resolution of the simulation grid
DYE_RESOLUTION: 1024, // Resolution of the dye grid
CAPTURE_RESOLUTION: 512, // Resolution of captured frames
DENSITY_DISSIPATION: 1, // Rate at which density dissipates
VELOCITY_DISSIPATION: 0.2, // Rate at which velocity dissipates
PRESSURE: 0.8, // Pressure value used in the simulation
PRESSURE_ITERATIONS: 20, // Number of pressure iterations
CURL: 10, // Curl value used in the simulation
INITIAL: false, // Enables splats on initial load
SPLAT_AMOUNT: 5, // Number of initial splats (Random number between n and n * 5)
SPLAT_RADIUS: 0.25, // Radius of the splats
SPLAT_FORCE: 6000, // Force applied by the splats
SPLAT_KEY: '', // Keyboard key to spawn new splats (empty to disable)
SHADING: false, // Enables shading in the visualization
COLORFUL: true, // Enables rapid changing of colors
COLOR_UPDATE_SPEED: 10, // Speed of color update
COLOR_PALETTE: ['#000000', '#000000', '#000000', '#000000', '#000000'], // Custom color palette (empty by default, uses hex colors)
HOVER: true, // Enables interaction on hover
BACK_COLOR: '#ffffff', // Background color of the canvas
TRANSPARENT: false, // Makes the canvas transparent if true
BRIGHTNESS: 1, // Color brightness (Recommend lower than 1.0 if BLOOM is true)
BLOOM: false, // Enables bloom effect
BLOOM_ITERATIONS: 8, // Number of bloom effect iterations
BLOOM_RESOLUTION: 256, // Resolution of the bloom effect
BLOOM_INTENSITY: 0.8, // Intensity of the bloom effect
BLOOM_THRESHOLD: 0.6, // Threshold for the bloom effect
BLOOM_SOFT_KNEE: 0.7, // Soft knee value for the bloom effect
SUNRAYS: false, // Enables sunrays effect
SUNRAYS_RESOLUTION: 196, // Resolution of the sunrays effect
SUNRAYS_WEIGHT: 1.0, // Weight of the sunrays effect
});
}, []);

I think that is a limitation of how the library calculates colors. I will take a look at a feature to fix it when I have time

I have a large upcoming rewrite of the package that solves this
