suggesting colored double ticks for read messages on telegram

Components

Telegram is an awesome app. With amazing features. I'm a frequent user of the app and I've enjoyed using it. Major activity on telegram is texting and getting replies from the other person. On telegram delivered message is signified with one tick and a read message by two ticks. Sometimes this read messages don't get replies. The double ticks still maintain the green color. So here's my suggestion.

Proposal

I'm suggesting that the double ticks system on telegram should be like this.
A sent message is signified with a tick, when it's delivered it'll be double ticks and when that message is read the double ticks changes color to signify that the message has been read.

Mockups / Examples

This is telegram app currently with only green colored double ticks.

This is telegram app with the suggested, colored double ticks on read messages. Now purple color.

Benefits

• with this function in place, users will be aware that their messages are read.
• It'll make the app look really good. Coloured double ticks would look sweet, especially if users can select a color of their choice.
