ShowTool Swatch brings your gel swatch book to life. It's the easiest and most beautiful way of viewing the information most important to you, helping you to make the right decisions when time matters. Share your ideas with friends or send orders straight to your local dealer.

ShowTool Swatch comes fully stocked with catalogues for Lee, Rosco, Gam and Apollo with updates as new gels are added.

Browse gels by manufacturer and range or search for a specific colour by name or number. Gels can be sorted by number or in catalogue order just like your old swatch book.

Gels are presented with the information you need most including name, number, transmission and RGB/CMY values along with a Spectral Energy Distribution graph and preview of the colour.

View and compare similar or complementary colours for those times when you've run out of your favourite colour or can't quite get the look you want.

Mark your favourite gels for quick and easy access or simply view a list of your most recently viewed gels. Notes can be added to each gel for when you just need a little reminder.

Collections provide a great way to group gels for a particular show or anything else that takes your fancy.

ShowTool Swatch comes complete with a selection of gel categories such as ‘Sunsets’ or ‘Moonlight’, great for those times when you need a little inspiration.

Use the superbly simple colour picker to find possible gel matches when you know the colour you want but can't remember it's number.

Ever see the perfect colour when you're out in the real world?! ShowTool Swatch has the answer with its exclusive photo-matching tool. Simply take a photo or use an existing one and see a great selection of gels that match your photo.

ShowTool Swatch comes complete with a comprehensive selection of dealers from across the US, UK and Europe for when you needed that gel yesterday! Create orders from existing collections and send a quote request directly from the app.

I love this more than I expected!

I only bought this because it was part of a bundle... But the reference for all gel colors is great! Each color gives you the correlating RGB and CMY values. Most recently, this helped me set specific LED colors for a client on a simple DMX fader board. It will display both RGB and CMY in 0-100% and 0-255 DMX values.

You can create personal color collections, favorite (or start) gel colors and easily access recently viewed gels. It's an excellent companion for any Lighting Designer, ME or just a stagehand who wants to advance their knowledge of lighting.

It even suggests complementary colors! Thank you for this great app!!

Thank You

This app has saved me lots of money already with the ability to offer gel substitutions to my lighting designer. Thank you for making such a great app.
