It is important to make sure that your documents are accessible to as many people as possible. Please write reports and other research documentation with accessibility in mind. For tutorials, checklists, and guidelines, see https://www.section508.gov/create/documents/
Excerpt from Texas Department of Information Resources https://dir.texas.gov/electronic-information-resources-eir-accessibility/eir-accessibility-roles-responsibilities/eir :
State agencies and institutions of higher education are required to comply with Texas EIR Accessibility statutes and rules to provide accessibility.
TGC 2054.451, enacted in 2005, requires that all state agencies and institutions of higher education, provide state employees and members of the public access to and use of electronic information resources.
1 TAC 213 enacted state standards for procurement, development, or usage of EIR for people with disabilities and also aligns accessibility standards with the federal regulations set forth in Section 508.

Non-text content (images and equations) must include alt text that screen readers can use to describe the content.

- A decision tree for creating alt-text https://www.w3.org/WAI/tutorials/images/decision-tree/
Before finalizing a document, screenshot and re-insert multi-component charts, graphs, equations, or Smart Art graphics so that alt-text can be added to describe the whole image instead of writing alt-text for each individual component (e.g., chart lines, arrows, photo collages, photos with overlay drawings, etc)

For complex equations that include matrices, layout, nested fractions, etc., It could be helpful to review samples the MathSpeak super-brief semantics to incorporate shorthand alt-text like
"StartFrac"/"EndFrac" bookends for identifying complex fractions https://www.seewritehear.com/accessible-mathml/mathspeak/examples/grammar-rules/?rule=fractions&description=Fractions&id=7
"StartRoot"/"EndRoot" bookends for identifying square root calculations https://www.seewritehear.com/accessible-mathml/mathspeak/examples/grammar-rules/?rule=radicals&description=Radicals&id=9
"l-par"/"r-par" or "l-brace"/"r-brace" for left- and right-parentheses or left- and right-braces
"Sub"/"Base" and "Sup"/"Base" for identifying the beginning and end of complex subscripts and superscripts, and "SupSup" to identify a superscript within a superscript: https://www.seewritehear.com/accessible-mathml/mathspeak/examples/grammar-rules/?rule=scripts&description=Superscripts%20and%20Subscripts&id=8

To test color contrast, you need the exact value for each color used. If testing colors that are on a website, try a color picker browser add-on to find this value. For desktop applications, free software such as Paciello Group's free Colour Contrast Analyser may help.
- Graph design, color, and accessibility
Bar Chart design, color, and accessibility
Even if you are color-coding charts, make sure values or labels are included with each bar for screen readers. If the color differences are significant to understanding the chart, make sure that they have sufficient color contrast and difference in darkness for a colorblind user to interpret.
Example 1. The below bar chart includes labels on each bar. Color contrast needs to be checked to make sure that there is enough contrast between the white text (foreground) and the red, orange, blue, and gray bars (background). In addition, if the bar colors are significant and correspond with a key, then the contrast between each bar color also needs to be checked.
- Checked on the Coblis free online colorblindness simulator. In this case, for readers with monochromacy, there is little to no difference between the orange and the gray bars. The difference between the red and the blue bars could also be easily confused.
To check the foreground (text) against the background (bar), check the color codes on WebAIM's Contrast Checker or other tool.
