With the introduction of the ADA (Americans with Disabilities Act) and DDA (Australian Disability Discrimination Act), it is useful for Architects, Interior Designers, Disability Access Consultants and even product manufacturers to quickly calculate the required LRV contrast of adjoining materials. Light / Luminance Reflectance Value, or LRV, is a measurement of light that is reflected from a surface. Some of the ways to find the LRV are by means of a colorimeter, spectrophotometer or directly by the manufacturer (for example, LRV noted on a fan deck provided by a paint manufacturer). LRV / Luminance Contrast is the light reflected from one surface as compared to the light reflected from another surface. This app calculates the percentage difference required when the LRV of any two samples are know. For example, if you have the LRV of the color of the door frame and the LRV of the color of the door, you can use this calculator to determine the contrast in % based on the formulas used in either USA or Australia. The Americans with Disability Act Accessibility Guidelines (ADAAG) recommends a 70% LRV or higher for those with impaired vision and Australian / New Zealand Standard AS/NZ 1428.4.1-2009 requires LRV contrast in a range of 30% to 60% based on the type of building elements. ## LRV Contrast Calculator Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/58/ee/d7/58eed769-2f57-0a57-dc40-40de9e1090f5/pr_source.png/1242x2688.png) ## LRV Contrast Calculator Rating Breakdown in Australia - 5 stars: 5 (83%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (17%) ## LRV Contrast Calculator Reviews in Australia ### ***** "Luminance contrast" This app is great to determine the luminance contrast requirements for compliance with DDA and the APS 2010. It provides the application of 30% to 60% as set out by the AS suite. Saves a lot of time and money at design stage for architects and interior designers, but also great for checking at completion of a project by applying the LRV value attached to the colour swatch. -- A1 NSW Accredited Certifier, 2017-04-12 [View all LRV Contrast Calculator reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to LRV Contrast Calculator - [Smart Tank](https://apptail.io/app/smart-tank-NOkb/australia) - [MyBINGO](https://apptail.io/app/mybingo-Pwse/australia) - [Pico](https://apptail.io/app/pico-MNNf/australia) - [Tint](https://apptail.io/app/tint-sIli/australia) - [LRV contrast reader](https://apptail.io/app/lrv-contrast-reader-qLli/australia) - [VPP: Powershop AU](https://apptail.io/app/vpp-powershop-au-yLCi/australia) - [Pooled.au](https://apptail.io/app/pooledau-VLCi/australia) - [iRecycle - Forbes](https://apptail.io/app/irecycle-forbes-jMCi/australia) - [Revival Cooperative](https://apptail.io/app/revival-cooperative-iNCi/australia) - [FINscore: Finska/Mölkky Scorer](https://apptail.io/app/finscore-finskamolkky-scorer-hrrn/australia) ## LRV Contrast Calculator Available In - [Australia](https://apptail.io/app/lrv-contrast-calculator-jNMl/australia) - [United States](https://apptail.io/app/lrv-contrast-calculator-jNMl/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
