Paper ballot (hand marked paper ballots and ballot marking devices for accessibility.)
Colorado votes by mail on paper ballots. The Office of the Colorado Secretary of State lists on their 2020 map of voting equipment a couple of counties that still use DREs with VVPATs.

Mix of hand count and retabulation
The canvassing board is required to test voting machines before a recount with the test results used to determine whether the ballots are retabulated using the same machines or recounted by hand. If the test reveals no unexplained discrepancy from a corresponding hand count, then retabulation is used, whereas any unexplained discrepancy results in a hand recount for the ballots that were counted on that machine, resulting in a mix of hand recounting and machine retabulation. Any batches of ballots that were initially counted by hand are also recounted by hand. 8 Code of Colorado Regulations (8 CRR) 1505-1 Rule 10.13.5(a)).
Rule 10.9.2 (8 CCR 1505-1) provides that “a county that has successfully completed a comparison audit under Rule 25.2 and reported no discrepancies in the recount contest need not re-scan ballots during a recount, except [by request of an interested party].” However, “in all cases, the county must re-adjudicate ballot images for voter intent” regarding “every overvote, undervote, blank vote, ambiguous mark, and write-in vote.”
Close vote margin
While election officials can't initiate recounts in Colorado, “the governing body that referred a ballot question or ballot issue to the electorate” may request a recount, even when the vote margin is not close enough to require the recount. C.R.S. 1-10.5-106(1).
Less than or equal to 0.5%
A recount is required when the "difference between the highest number of votes cast in that election contest and the next highest number of votes cast in that election contest is less than or equal to one-half of one percent of the highest vote cast in that election contest." C.R.S. 1-10.5-101(1)(b).
Timing: Recounts for congressional, state, and district offices, state ballot questions, and state ballot issues see C.R.S. 1-10.5-102, Subsections (1) and (2). Recounts for contests and questions under county jurisdiction see C.R.S. 1-10.5-103. Recounts for nonpartisan elections not coordinated by the county clerk and recorder see C.R.S. 1-10.5-104.
Recounts for issues and questions in Colorado are not requested by voters at large, but only by those who either originally served as designated representatives when the petition for the question or issue was circulated or are “the agent of an issue committee that is required to report contributions” and supported or opposed the question or issue. C.R.S. 1-10.5-106 and C.R.S. 1-40-113. Such representatives and agents qualify as “interested parties” and may request recounts in accordance with the rules set out for candidate-initiated recounts.
Initiator pays deposit or bond before recount
Payer of costs depends on outcome of recount
Costs are not determined before the election but determined before the recount by the respective election official with whom the candidate has filed their recount request. The candidate must pay the full amount before the recount begins. All funds are returned to the initiating party if the election results are reversed in their favor, or if they are sufficiently changed such that a close vote margin recount would have been warranted. C.R.S. 1-10.5-106.
Party/candidate or initiator has statutory authority to appoint observers
No statutory guidance for recount challengers
Political parties, candidates, and those sponsoring issues and questions are allowed to have designated “watchers” during the initial counting process, but the statutes do not clarify if such watchers are also allowed during recounts. C.R.S. 1-7-105, 1-7-106, and 1-7-107. The Secretary of State's regulations, however, clarify that watchers may also be present at recounts. 8 CCR 1505-1 Rule 8.10.2(a)(11). Rule 8.3 also clearly states that political party attorneys are not allowed into counting locations unless formally registered as a watcher. Neither the state statutes or rules specifically grant watchers the ability to challenge ballots. However, Rule 8.16 provides that “Unless the county clerk has established another process, if a watcher disputes a decision made by an election judge or alleges a discrepancy, the watcher must alert the designated watcher contact.” Also, those initiating a recount or who are party to one may challenge the entire process in the appropriate district court. C.R.S. 1-10.5-109. We found no statute requiring that the recount be conducted publicly; however, 8 CCR 1505-1, Rule 8.18 provides that “Media Observers may witness all election activities.”
