Colour Details
CIE 1931 Chromaticity Diagram: Displays the color space with the light source's white point (6564 K) indicated. A zoomed view shows the light source's position relative to the Planckian locus, with a color deviation (Δuv) of 0.0002.
TM-30: 62.9. This index measures color fidelity. Bar charts show the R values (R1-R15) used in CRI calculations and TM-30 values (C1-C16) across different color bins.
CRI: 65.0 (R1-R8). Color Rendering Index, indicating the ability of the light source to reproduce colors accurately compared to a natural light source. Bar charts illustrate individual R values.
CQS: 59.6. Color Quality Scale, another metric for color rendering. Bar charts display Q values.

TM-30 Details
Fidelity Index Rf: 62.9. Measures the accuracy of color rendering.
Gamut Index Rg: 86.7. Measures the saturation of colors.
The document includes a table detailing Rf and Chroma/Hue shifts for 16 hue bins. Bar charts visualize 'Rf by hue' and 'Chroma shift by hue', showing how color rendering varies across the spectrum. Descriptions of 'Color vector graphics' and 'Color distortion graphics' are provided, likely representing 3D color space renderings. A bar chart for 'Fidelity Index, Rf' across various 'Color Evaluation Samples' is also presented.
| Hue Bin | Rf | Chroma Shift (%) | Hue Shift (%) |
|---|---|---|---|
| 1 | 58 | -23% | -1% |
| 2 | 66 | -17% | 11% |

TLCI and Color Swatch Analysis
TLCI: 36. The Television Lighting Consistency Index measures how well a light source renders the colors of a television camera.
The document presents a grid of color swatches, each representing a specific color or skin tone (e.g., Dark skin, Light skin, Blue sky, Foliage, Red, Blue, White, Black). Associated percentages and values are provided for each swatch, indicating their measured accuracy or performance under the light source, such as 'White 90.01%', 'Neutral 8, 59.1%', 'Neutral 6.5, 36.2%', etc.
