Analysis

Overview

The user should be able to pick custom color as well as predefined swatches from this dialog.

Task requirements

There are 3 main parts

• The preview - The changes of the selected color should be visible run time. It will be best if the previous color is visible as well as the new one.
• Swatches section - user should be able to select from predefined as well as from custom defined swatches. Also there should be ability for the user to add, delete end edit the set of custom swatches. It will be great if he could save and load these sets.
• Color select section - user should be able to select the color from color plane and horizontal color slider. Also he could type the exact value via RGB, HSB and hex number. There should be input fields for red, green, blue, hue, saturation, brightness and hex number. There should be restrictions for these fields as follows:
  • red, green and blue - value can be number between 0 and 255
  • brightness and saturation - value can be number form 0 to 100
  • hue - value can be number between 0 and 359
  • hex number text field - only hex numbers are allowed

All elements in 'color select section' should update them selfs runtime. It will be great if vertical slider appears after the user rolls over the right part of the input fields that allowed only numbers values.
