How are people getting screenshots w/ color

[masterz87]

Seriously are they doing post-processing and colirizing their screenshots or something? Or does the system itself actually show images/covers etc in color before rendering it on the screen? I would've imagined they'd convert them to grayscale to save memory/time since it's going to be grayscale anyway once it's rendered.

That one ^. Using the device to take a screenshot is like making a recording with a colour VCR while watching a show on a black-and-white TV. The video tape will be in colour, because it is recording the colour transmission and not what is on the TV screen.

If the image on the device is in colour then it is probably faster just to display it as a colour image than it is to convert it to greyscale first.

It used to be that covers downloaded to e-ink devices from the Kobo server were all in greyscale anyway, and that made sense since it reduced download time and storage requirements. But it seems that some covers are now coming through in colour, I can't understand why they would do that on purpose, maybe it is just a mistake.

If sideloading from Calibre there is an option to send greyscale cover images.

Perhaps they're putting things in place to, in the future, have some type of color device that uses the same software.

Well that makes sense then, but the kobo images folder are all black and white.

There are a lot of people who read epubs in tablets or smartphones. The ebooks shops are thinking of them too.

Perhaps, but the devices already download different covers to suit their screen size, so a colour device could download colour covers without the need to send them to greyscale devices.

The images inside the books are not changed, they have always been in colour. The greyscale covers that are downloaded from the server are used outside the book, e.g. on the sleep screen or as thumbnails in the library view. They are downloaded specially for each device so there is no need for them to be in colour if the device downloading them doesn't have a colour screen.
