Generates synthetic tasks where two colored light sources are shown on the left and right. The goal is to calculate the additive color mixing result and fill the center mixing zone with the resulting color.
Each sample pairs a task (first frame + prompt describing what needs to happen) with its ground truth solution (final frame showing the result + video demonstrating how to achieve it). This structure enables both model evaluation and training.

The scene has two colored light sources positioned on the left and right sides, and a mixing zone marked by a white rectangular border in the center. In additive color mixing (light mixing), when two lights overlap, their RGB components add together: result_R = min(color1_R + color2_R, 255), same for G and B, with each channel clamped to 255 maximum. First identify the RGB values of the left light (an RGB(127, 47, 114) colored light) and the right light (an RGB(111, 111, 52) colored light), then calculate the mixed color by adding their RGB components channel by channel. Fill the white-bordered mixing zone in the center with the resulting mixed color and show the full calculation process step by step.

Calculate the additive color mixing result of two colored light sources and fill the center mixing zone with the resulting color. This generator involves color calculations and modifications through additive color mixing, demonstrating understanding of color theory and RGB color space operations.
- Light Sources: Two colored lights positioned on left and right sides (closer to edges, radius 280px)
- Each light source has a solid center (30% of radius) in its own color
- Radial gradient from center to edge for glowing effect
- Mixing Zone: White-bordered rectangular area in the center
- Color Model: Additive RGB color mixing (light mixing)
- Calculation: result_R = min(color1_R + color2_R, 255), same for G and B
- RGB Range: Each color channel ranges from 0-128 for input colors (to avoid always getting white when mixed)
- Display: Show step-by-step calculation process
- Additive color theory: Tests understanding of how light colors mix
- RGB calculation: Requires channel-by-channel addition with clamping
- Mathematical reasoning: Applying arithmetic operations to color channels
- Visual representation: Translating calculation result to visual color
- Step-by-step solution: Animation demonstrates the mixing process
- Clamping logic: Understanding that RGB values are capped at 255
