(Red, Green, Blue) color mode is for anything that is computer-based design. This includes websites, apps, banner ad and any other design created for electronic use.
(Cyan, Magenta, Yellow, Black) color mode is used for print design. This includes logos, business cards, stationary, illustration, packaging and any other designs used for print.
A hex color code is a way of specifying color (RGB) using hexadecimal values. The code is generally associated with HTML and websites.
Vector images are made up of points, lines, and curves that can be infinitely scaled without any loss in image quality.
Raster images are made up of a set grid of dots called pixels, where each pixel is assigned a color value. Unlike a vector image, raster images are resolution dependent. When you change the size of a raster image, you shrink or stretch the pixels themselves, which can result in a significant loss of clarity and produce very blurry images.
Lossy image formats approximate what your original image looks like. For example, a lossy image might reduce the amount of colors in your image or analyze the image for any unnecessary data. These clever technical tricks will typically reduce the file size, though they may reduce the quality of your image.
Lossless image formats capture all of the data of your original file. Nothing from the original file, photo, or piece of art is lost—hence the term “lossless.” The file may still be compressed, but all lossless formats will be able to reconstruct your image to its original state.
PNG is a lossless raster format that stands for Portable Network Graphics. Think of PNGs as the next-generation GIF. This format has built-in transparency, but can also display higher color depths, which translates into millions of colors. PNGs are a web standard and are quickly becoming one of the most common image formats used online.
JPEG is a lossy raster format that stands for Joint Photographic Experts Group, the technical team that developed it. This is one of the most widely used formats online, typically for photos, email graphics and large web images like banner ads. JPEG images have a sliding scale of compression that decreases file size tremendously, but increases artifacts or pixelation the more the image is compressed.
EPS is an image format that stands for Encapsulated PostScript. Although it is used primarily as a vector format, an EPS file can include both vector and raster image data. Typically, an EPS file includes a single design element that can be used in a larger design.
