RGB Color Table

Class has learned that Additive Color onscreen has primary colors Red-Green-Blue (RGB). And computers understand each color as a string of 6 numbers: RRGGBB. The settings in Photoshop range from 0 to 255. Computers understand these numbers in hexadecimal (counting by 16) as 00 to ff. For now we will limit ourselves to “browser-safe” settings of 00, 33, 66, 99, cc and ff.

Each student will be assigned a “fixed color” (example: Red at FF) and create a Photoshop color table of all 36 browser-safe colors that use that fixed color.

Create a new file in Photoshop 600px x 600px @72ppi.

View > Rulers

Photoshop > Preferences > Units & Rulers >
change Ruler Settings to PIXELS

Then place guidelines (both horizontal and vertical) at every 100 pixels.
