Question

Which is the appropriate (more readable) way of naming enumerator? will you consider:

enum FilterOperators
{
    IsEqual, 
    Contains, 
    StartsWith
}

class QueryFilter
{
    FilterOperators Operator{get;set;}
}

var filter = new QueryFilter();
filter.Operator = FilterOperators.IsEqual;

Or is this preferable

enum FilterOperatorType
{
    IsEqual, 
    Contains, 
    StartsWith
}

class QueryFilter
{
    FilterOperators Operator{get;set;}
}

var filter = new QueryFilter();
filter.Operator = FilterOperatorType.IsEqual;

Also, Colors or ColorType?

IrritatedVowel.com suggests the following:

Enumerations

Standard Based Upon Microsoft .NET Library Standards

Follow class naming conventions. Do
not add “Enum” to the end of the
enumeration name. If the enumeration
represents a set of bitwise flags, end
the name with a plural.

Why: This convention is consistent
with the .NET Framework and is easy to
read.

Example:

SearchOptions (bitwise flags)

AcceptRejectRule (normal enum)

As such, I believe the preferred choice would be FilterOperator.
