> Shadecard for Android 0.9 brings a redesigned home screen, plain white paper as the everyday reference, and a shade library that grew from 466 to 13,297 shades.

Shadecard for Android 0.9 brings three headline changes: a **redesigned home screen** built around one button, **plain white paper** as the everyday reference instead of a grey card, and a **shade library that grew from 466 to 13,297 shades** – about 28 times the size – so almost any cloth lands close to a named shade and its recipe.

## One button to start

The new home screen puts **Capture dress color** front and centre, with your remaining scans underneath (**3 scans left · Get more** on a fresh install). Below it, a **Toolkit** of four tiles:

- **Shade library** – 13,297 shades to browse
- **Recipe calculator** – grams, stock or pad liquor
- **My workspace** – readings, dips and favourites
- **Scan packs** – your scan balance

Further down, **How it works** explains the three steps – Photograph, Measure, Recipe – and **Good to know** repeats the rule the app is built on: a phone is not a lab instrument, and every recipe ends with a small test batch.

A reference of known colour in the frame is what turns a phone photo into a measurement. Plain **white printer paper** is now the default reference: lay it in the small box beside the fabric, and it corrects the light's tint and anchors how dark the fabric really is – enough to unlock the full result, shade plus recipe. The **18% grey card** and the **24-patch colour chart** are still there for tighter, more repeatable readings.

## 13,297 shades, and why the number stops there

The library now holds 13,297 shades across six families:

FamilyShadesGreens3,168Purples & violets2,561Browns & neutrals2,239Blues & teals2,117Reds & pinks1,845Oranges & warm tones1,367Each shade has a yellow:red:blue ratio and a typical depth. The library was grown in stages, each one checked by automated gates:

- **No near-duplicates:** every pair of shades is at least 1.3 ΔE00 apart.
- **No holes:** nowhere in the core region where real garment colours live is more than 3 ΔE00 from a library shade.
- **Every shade findable:** each shade must come back as its own best match.

13,297 is where those gates meet: in the final pass, no remaining position in the gated gamut passed both the spacing check and the self-match check, so any further shade would in effect duplicate one already there.

To be clear about what the shades are: **101 are hand-curated**, and the rest are **coverage-fill shades** placed to close the gaps, with ratios interpolated from the curated shades around them. All library colours are illustrative values, not dyed swatches read on a spectrophotometer. Every recipe remains a starting point for a lab dip.

Also in the library:

- **Hex search** – type a code like *A1B2C3* to see the nearest of 144,380 fine-grid reference points with derived recipes.
- **ISCC-NBS names** – each shade page shows its nearest standard colour name, such as *Moderate Olive*.
- **Printable PDF shade cards** – one tap per family, 72 swatches per A4 page.
- **Urdu names** for the curated shades, searchable in Urdu.

## From ratio to grams

The **Recipe calculator** expresses the same recipe three ways: **Weigh (g)** for batches, **Stock (mL)** for pipetting lab dips from stock solutions, and **Pad (g/L)** for continuous dyeing – with the bath volume, salt and soda ash worked out for reactive dyeing on cotton. Open it from any result with **Work out the amounts**. [Use the recipe calculator](https://abdohoo.app/help/shadecard/recipe-calculator).

## All of it in Urdu

One tap on **اردو** switches the whole app, right to left – not just the buttons, but the capture coaching, the refusal messages, the recipe hints and the dyeing terms. [Switch Shadecard to Urdu](https://abdohoo.app/help/shadecard/switch-to-urdu).

## Also in this version

- **Match closeness meter** on every matched result, with the ΔE00 and zones for close, rough and far.
- **Share recipe card** – a picture with swatch, Lab, ratio, depth and the lab-dip reminder, ready for WhatsApp.
- **Light check** – re-read the same cloth with the torch to see whether the reading is light-sensitive.
- **Dip log and Right first time** – record lab-dip outcomes and corrections in **My workspace**; after three dips in a dye class and family, the app adjusts its suggestions to your process.
- **Custom shades** – promote an approved recipe; it joins matching, badged *user shade*.
- **Cloud backup** – sign in and your measurements, dips and shades back up automatically.

## Scans

A new install includes **3 free scans**. A scan is counted only when a fresh capture produces a result – rejected captures and light checks are free. After that, scan packs are bought through Google Play; paid scans include an optional AI second opinion. The library, calculator and workspace never use scans. [Android app, website and scan packs](https://abdohoo.app/help/shadecard/android-app-website-and-scans).

## A good first session with 0.9

If you are trying the new version for the first time:

1. Switch the language to the one your team works in, using the **English | اردو** switch on the home screen.
2. Take one reading of a plain, known fabric with **White paper** in the small box, and look at the spread and the match closeness.
3. Open the matched shade in the **Shade library**, look at its **Visually similar** neighbours and compare one of them.
4. Tap **Work out the amounts**, switch the calculator to **Stock (mL)**, and set it to your usual lab swatch weight.
5. Save the measurement, run the lab dip, and log the result in **My workspace**.

That covers every part of the app in one loop – and ends where every recipe should end.

## Still honest about its limits

Nothing here turns a phone into a spectrophotometer. Shadecard still refuses a recipe without a reference card, rejects captures whose three photos disagree by more than ΔE 3, names no shade when the nearest is more than ΔE 9 away, and ends every recipe with *confirm with a lab dip*. See the product site, [sc.abdohoo.app](https://sc.abdohoo.app), for a demo of the measurement.
