Question

public List<HistoryTimelineObject> processTimelineItem(id recordId, Integer pageNo, Integer pageSize){
    List<HistoryTimelineObject> wrappedCase = new List<HistoryTimelineObject>();

    List<Case> t = [SELECT Id, Subject, AccountId, CreatedDate, CreatedBy.Name
    FROM   Case
    WHERE  Applicant__c = :recordId
    LIMIT :pageSize
    OFFSET :pageNo];
    if(t != null){
        for(Integer i = 0, CaseSize = t.size(); i < CaseSize; i++){
            wrappedCase.add(new HistoryTimelineObject().setActor(t[i].CreatedBy.Name)
                    .setHeader(t[i].Subject)
                    .setDate(t[i].CreatedDate.format())
                    .setIconName('standard:case')
                    .setIconColour('put the colour in here'));

        }
    }

    return wrappedCase;
}
