Description

P L E A S E R E A D B E F O R E Y O U B U Y!!!

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

---OR---

LRV Guru™ app MEASURES Light Reflectance Value (LRV) when integrated with Variable, Inc.'s Color Muse hand-held colorimeter. Guru also works with the Node+Chroma.

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

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

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

FEATURE: You can adjust the contrast ratio. LRV Guru's default contrast ratio is set at 70% because it is the most commonly applied guideline. 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.

What's New in Version 1.3.1

Customer Reviews

Great idea!

Love the LRV Guru app idea, but it is not connecting my iPhone to the Color Muse. I have the latest update and latest operating system upgrade. Is there a fix?
