When creating a new document set to profile: Web, what are the default color mode and raster effect settings?

When creating a new document in Adobe Illustrator with the profile set to Web, the default color mode is RGB, and the default raster effects settings are set to 72 ppi (pixels per inch).

The RGB (Red, Green, Blue) color mode is used for digital content because screens emit light, and the RGB model accurately represents colors as they appear on screens. This is particularly important for web design, where the final output is intended for display on monitors and devices that rely on light.

The raster effects settings of 72 ppi are optimized for web use, as this resolution provides a balance between image quality and file size, ensuring that web graphics load quickly without compromising too much on visual clarity.

In web contexts, high resolution is generally not necessary since screens typically display at 72 ppi, and higher settings could lead to unnecessarily larger file sizes, which can negatively affect loading times and performance on the web.
