[color=#999999]This activity belongs to the [i]GeoGebra book[/i] [url=https://www.geogebra.org/m/JexnDJpt]Lights Out (Games with solutions)[/url].[/color][br][br]Now we propose the following game: try to reproduce [i]exactly [/i]a certain color, the one with the upper rectangle. To do this, you have the R, G, B (red, green, blue) sliders that allow you to vary the color of the lower rectangle.[br][br]Only when the two rectangles have exactly the same RGB color will the message that you have achieved it appear.[br][br]If you find it too difficult, you can choose to display a hint that will guide you to the desired color.
