A basic display of how LCD screens use colours. (LCD just stands for liquid crystal display and I have no idea what that means) It has no purpose, but it might educate you on how screens work, I guess. It's funny bc you're viewing it on a screen..... Click green flag to start. Click square in top left for settings, click again to shut it. Click green flag once you have changed any of the settings. (except for the red, green, and blue) The versions - the only difference is 1 has all the colours in the same costume, in 2 all the colours are separated, so the screen's colour can be changed depending on how much of each colour there is. (I didn't just use 'change colour effect' block!). It defaults to version 2. VERSION 1 - Click the screen to change the costume (shape of the colours). Click the stop button to view the shape. There is circles, diamonds, and lines, & smth else. VERSION 2 - This type can change the colour of the screen by changing how visible the red green and blue are. Once it's stopped doing it's mosaic thing, it will go through the rainbow. Try doing it on a lower scale (e.g repeats 10 mosaic 20). The lower the repeats, the faster it will mosaic. (you can do 1 repeat to do it instantly, but I like watching it). After it's done its rainbow thing, you can change the red, blue and green values in settings. (This changes how visible the sprites are). I might add so you can change the costume. Note - on a normal screen, obviously it can show you an image, but this can't because it's all the same sprite. (I tried to make tons of tiny clones but there's a clone limit). Note - the mosaic effect has a limit. I think it looks quite cool :) I made this because I heard about the colour thing and I wanted to test it. It’s really simple, look inside -> Short Explanation: From what I know… your eyes can recieve red, blue and green light, so the way screens can make you view all the different colours is by having those 3 colours in different amounts in each tiny pixel, which can make all visible colours. But they are so small you can’t see the individual colours, and it looks like a different colour. Also this isn't exactly what screens look like often they are in different formations to the ones shown...... but it's the basic idea.
