Hello, There are many discussions on how to map locations with google maps prior to the spring 2015 release, but now that apex:map and apex:mapmarker are available, I would like to figure out how to modify the marker color using that to bring in a new map rather than the javascript methods that have been previously used.

I currently importing the map to account pages with this code on the visualforce page:
 

<apex:page standardController="Account" extensions="accountMapExtensionTwo">

  <!--This page must be accessed with an Account Id in the URL. -->
  
  <apex:map width="600px" height="400px" mapType="roadmap">

    <apex:repeat value="{!Accounts}" var="acct">
        <apex:mapMarker title="{!acct.name}" position="{!acct.loc}"/>
    </apex:repeat>

  </apex:map>
  

</apex:page>



<!--<apex:page standardController="Account" extensions="accountMapExtension">

  This page must be accessed with an Account Id in the URL. 
  
  <apex:map width="600px" height="400px" mapType="roadmap">

    <apex:repeat value="{!Accounts}" var="acct">
        <apex:mapMarker title="{!Accounts[acct].Name}" position="{!Accounts[acct].BillingStreet},{!Accounts[acct].BillingCity},{!Accounts[acct].BillingState}"/>
    </apex:repeat>

  </apex:map>
  

</apex:page>-->

I then have an apex class that uses this code:
 

public class accountMapExtensionTwo {

    private final Account account;
    
    public accountMapExtensionTwo(ApexPages.StandardController stdController) {
        this.account = (Account)stdController.getRecord();
    }
    
    List<DisplayAccounts> Accts;
    
    public List<DisplayAccounts> getAccounts() {
        
        Map<Id,Account> mapList = new Map<Id,Account>();
        Set<Account> childList = new Set<Account>();
        Set<Id> parentId = new Set<Id>();
        
        Accts = new List<DisplayAccounts>();

        for(Account a : [SELECT Name, Location__longitude__s, Location__latitude__s, Parent.Id, BillingStreet, BillingCity, BillingState, (SELECT Name, Location__longitude__s, Location__latitude__s, BillingStreet, BillingCity, BillingState FROM ChildAccounts) FROM Account WHERE Id = :ApexPages.currentPage().getParameters().get('Id')]){
            
            accts.add(new DisplayAccounts(a));
            
            mapList.put(a.id,a);
            
            parentId.add(a.Parent.id);
            
            for(Account acc : a.ChildAccounts){
            
                accts.add(new DisplayAccounts(acc));
                
                mapList.put(acc.id,acc);
            }
        }
        
        List<Account> mapValueList = new List<Account>();
        mapValueList = mapList.values();
        
        for(Account a : [SELECT Name, Location__longitude__s, Location__latitude__s, BillingStreet, BillingCity, BillingState, (SELECT Name, BillingStreet, BillingCity, BillingState  FROM ChildAccounts) FROM Account WHERE Id IN :mapValueList]){
            
            for (Account acc : a.ChildAccounts){
            
                accts.add(new DisplayAccounts(acc));
                
                mapList.put(acc.id,acc);
            }
        }
        
        for(Account a : [SELECT Parent.Id FROM ACCOUNT WHERE Id IN :parentId]){
            parentId.add(a.Parent.Id);
        }
        
        for(Account a : [SELECT Name, Location__longitude__s, Location__latitude__s, BillingStreet, BillingCity, BillingState FROM Account WHERE Id IN :parentId]){
            
            accts.add(new DisplayAccounts(a));
            
            mapList.put(a.id,a);
        }
        
        return accts;
        
    } 
    
    public class DisplayAccounts {
        private Account acct;
        public DisplayAccounts (Account a){
            this.acct = a;
        }
        
        public Map<String,Double> loc {
            get { return 
                new Map<String,Double>{
                    'latitude' => acct.Location__latitude__s,
                    'longitude' => acct.Location__longitude__s
               };
           }
       }
       
       public String name {
           get { return acct.Name;}
       }
       
    }
}

This works perfect for what I'm trying to do, I should note that I'm using geocode for the map marker location.

This code lets you map multple places on an account page, by selecting the parent/child relationship that the accounts are a part of, translating the address for those accounts to geocode, and then displaying the points on a map of a parent account and it's child accounts..

What I'm running into however, is there is almost no documentation on how to change the color of apex:mapmarker. What I would like to do is set it up so that I can change the color of the mapmarker based on a custom field variable. I would also like to potentially change the color of the markers based on the parent/child relationship. However, any help at all on how to change the color/marker icon of apex:mapmarker would be greatly appreciated.

Thank you!
