Fix color contrast - chart labels

[ckundo]

Problem

Chart labels (#1031, #1035, etc.) have insufficient contrast ratio of 2.26:1, failing WCAG AA requirement of 4.5:1.

Files to Update

• CSS file (chart label styles)

Current Values

• Color: rgb(160, 174, 192) (#a0aec0)
• Background: rgb(255, 255, 255) (#ffffff)
• Contrast Ratio: 2.26:1 ❌
• Required: 4.5:1 for normal text

Tasks

• Change chart label color from #a0aec0 to #637894
• Verify new contrast ratio is 4.52:1 (passing)
• Test visually to ensure readability

WCAG

1.4.3 Contrast (Minimum) (Level AA) - Text must have 4.5:1 contrast ratio

Recommended Fix

.chart-label {
  color: #637894; /* Instead of #a0aec0 */
}

Expected Outcome

Chart labels are readable for users with low vision
