ComfyUI Node: Particle Color Modulation | RyanOnTheInside

Particle Color Modulation | RyanOnTheInside:

The ParticleColorModulation node is designed to dynamically alter the color of particles within a particle system over time. This node allows you to specify a target color that particles will gradually transition to, creating visually appealing effects such as color fades or shifts. By modulating particle colors, you can enhance the visual complexity and aesthetic appeal of your particle-based animations or simulations. This node is particularly useful for creating effects where the color change is synchronized with other particle properties like size or speed, providing a cohesive and engaging visual experience.

Particle Color Modulation | RyanOnTheInside Input Parameters:

target_color

The target_color parameter specifies the color that the particles will transition to over the course of the modulation. This parameter accepts a string in the format (R,G,B), where R, G, and B are integers representing the red, green, and blue components of the color, respectively. The default value is (255,255,255), which corresponds to white. Adjusting this parameter allows you to control the final color of the particles, enabling you to create a wide range of color effects. For example, setting the target color to (255,0,0) will make the particles transition to red.

Particle Color Modulation | RyanOnTheInside Output Parameters:

PARTICLE_MODULATION

The PARTICLE_MODULATION output is a modulation chain that includes the color modulation settings. This output is used by the particle system to apply the specified color changes to the particles over time. The modulation chain contains all the necessary information for the particle system to interpolate the particle colors from their original state to the target color, based on the progress of the modulation.

Particle Color Modulation | RyanOnTheInside Usage Tips:

• To create a smooth color transition effect, ensure that the effect_duration parameter in the modulation settings is set to a value that allows the color change to occur gradually over the desired time period.
• Combine color modulation with other types of particle modulations, such as size or speed, to create more dynamic and visually interesting effects.
• Experiment with different target_color values to achieve various visual styles and moods in your particle animations.

Particle Color Modulation | RyanOnTheInside Common Errors and Solutions:

ValueError: A Particle Color Modulation | RyanOnTheInside already exists in the chain.

• Explanation: This error occurs when you attempt to add multiple ParticleColorModulation nodes to the same modulation chain.
• Solution: Ensure that each modulation chain contains only one ParticleColorModulation node. If you need to apply multiple color changes, consider chaining different modulation types or adjusting the modulation settings to achieve the desired effect.

Invalid color format for target_color.

• Explanation: This error occurs when the target_color parameter is not provided in the correct (R,G,B) string format.
• Solution: Verify that the target_color parameter is specified as a string in the format (R,G,B), where R, G, and B are integers between 0 and 255. For example, use (255,0,0) for red.
