LRV Guru for Pc

1. LRV is Light Reflectance Value and LCh° is Lightness, Chroma, and Hue Angle which means you can download The Color Strategist color wheel and determine what hue family a color belongs to.

2. LRV Guru™ app MEASURES Light Reflectance Value (LRV) when integrated with Variable, Inc.'s Color Muse hand-held colorimeter.

3. The spectral data captured with the Color Muse and the values and/or ratios ascertained using the LRV Guru app are reasonably informative guidelines - "in the ballpark", as they say.

4. A picture of a color is just a captured image, it is NOT A MEASUREMENT! To MEASURE LRV using this app, you must use a Color Muse or NODE+Chroma hand-held colorimeter.

5. Beyond reasonably informative guidelines would require certified measurements from a color lab.

6. NOTE: You cannot take a picture of a color with your smartphone or camera and ascertain LRV.

7. A significant bonus feature of the app is that the contrast ratio can be adjusted by tapping "settings" and positioning the slide bar as desired.

8. LRV Guru's default contrast ratio is set at 70% because it is the most commonly applied guideline.

9. LRV Guru™ app can be USED ALONE to calculate known LRV value differences.

10. FEATURE: You can adjust the contrast ratio.

11. LRV and LCh° are displayed via the "Compare" option from the menu.
