The concepts "<developer> assigned <expression> to a <type> object"
and "<expression> can be assigned to a <type> variable" just don't
exist in Python.
# Initially "name1" isn't bound to anything
name1 = 42
# "name1" now refers to an int object whose value is 42
name1 = 'abc'
# "name1" now refers to a str object whose value is 'abc'
name2 = name1
# "name2" now refers to the same str object
What is "dialog.colorDialog(self) return value"? What is "a result
object"? Show us the code!
What is the connection between your last sentence above and the
"TypeError: list indices must be integers" problem? Show us the code!

Communication would be much easier if you show us the line of code
that causes the error message.
Here are two simple examples of what can trigger that error message:
>>> a_list = [1, 42, 666]
>>> not_an_integer = None
>>> a_list[not_an_integer] = 9876
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list indices must be integers
>>> a_name = a_list[not_an_integer]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list indices must be integers
Look for the pattern a_list[not_an_integer] in the statement that
triggers the exception.

Yes, that's most likely a tuple of (red, green, blue) values ... I'm
not astonished; are you?
> How to covert result.color into a string?
How? Use elementary Python functionality, after you've decided what
string representation you want. Examples:
>>> color = (255, 128, 0)
>>> "red=%d green=%d blue=%d" % color
'red=255 green=128 blue=0'
>>> '.someclass {background-color: #%02x%02x%02x; }' % color
'.someclass {background-color: #ff8000; }'
>>>

Reverse the process.
Again, what is the connection between "result.color" and the
"TypeError: list indices must be integers" problem?
