3:1 contrast ratio for 18 point font

Test Case Summary

Test Case ID

TC8.1-3-pass-1

Test Case Description

Detect the foreground and background text and size contrast ratio. Determine whether contrast ratio is sufficient based on size and weight of the font. The text in the code sample is 18 point font with sufficient contrast at greater than 3:1 between the foreground and background.

Applicable ICT Baseline Test

8.1 Test Procedure for Contrast Minimum

Baseline Test ID: 8.1-ContrastMinimum

Test Instruction: 3

Test Case Detail

Expected Baseline Result

Pass

The foreground text in the code sample provides sufficient contrast (greaer than 3:1) based on the text size (18 point font), foreground color, and background color.

Test Case Instruction

Test Instruction	Instruction Detail	Expected Test Case Result
IC	All visible text AND images of text (except those noted in Limitations, Assumptions, or Exceptions)	Sample code of text is present for this test
8.1-1	Determine the contrast ratio of foreground text and background.	The contrast ratio for the text is 3.8:1
8.1-2	Check that the contrast ratio is at least 4.5:1. [SC 1.4.3]	The contrast ratio is less than 4.5:1 (it is 3.8:1)
8.1-3	If the contrast ratio is less than 4.5:1, check that the ratio is at least 3:1 AND the font meets one of the following criteria: [SC 1.4.3] At least 18 point (23.94 pixels); At least 14 point (18.62 pixels) AND bold (at least 700 font weight)	The contrast ratio is greater than 3:1 (it is 3.8:1)
Test Results	If both of the above checks fail, then Baseline Test 8.1-ContrastMinimum fails.	The sample code passes check 8.1-3, therefore the code PASSES
