Do blocked iMessages turn green? Check the bubble color
iMessage users know that a green bubble indicates that you’re sending a regular text message instead of using Apple’s proprietary messaging protocol — what might be news is that green bubbles can also be an indicator that someone has blocked you on iMessage.
Why did my iMessage suddenly turn green? If your iPhone messages are green, it means that they’re being sent as SMS text messages rather than as iMessages, which appear in blue. iMessages only work between Apple users. You’ll always see green when writing to Android users, or when you’re not connected to the internet.

iMessage is turned off on your device or on your recipient’s device. To check if iMessage is turned on for your device, go to Settings > Messages > iMessage. iMessage is temporarily unavailable on your device or on your recipient’s device.
Why does iMessage turn from blue to green? You may have noticed that the text messages in your iPhone’s Messages app can appear as either green or blue. The difference? Green messages are ordinary SMS text messages, while blue messages are using Apple’s proprietary iMessage format.
