Colour Simulations
Simulate colour vision deficiency

Colour Simulations is a free tool which can simulate - or help counter - various types of colour vision deficiency.

Designers could use the program to understand how people with common red-green colour vision conditions (deuteranomaly and protanomaly) might see their creation. Someone with those conditions might use it to help them see colours more clearly, and the program could also be handy to anyone who wants to tweak screen colours occasionally.

Colour Simulations works by displaying a movable, resizable filter over the screen. Right-click this and you're able to choose a colour vision deficiency, or colour transform you'd like to apply (Brightness; Contrast; Saturation; Greyscale; Invert; Circadian light block; Colour swaps and filters). Then spin the mouse wheel to maximise or minimise the effect.

This is mostly designed for occasional use, but you can also maximise the filter window (press H to make it hit-transparent, F for full-screen). Browse the web, watch videos, use other applications and their colours will be adjusted in real-time to match your settings.


Colour Simulations provides an interesting way to learn more about colour vision deficiency. It can also compensate for those conditions and other issues, although if you just want a colour filter for your screen there are simpler tools around.

WhatsApp Messenger 2.17.51

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.
