[R] chi square test is not appropriate? but what test is

Hallo all

Suppose I have a summary amount of various colours used in 
different areas

colour	plastic	paint
black	15.5	173.8
brown	6.0	523.2
green	2.5	6.4
red	77.1	237.4
yellow	144.6	77.3

It seems that there are some preferable colours in these two areas 
(yellow in plastic, brown an red in paint).

The problem seems to me similar to chi square test but it is 
intended for testing counts or frequencies (if I understand it well).

If I wanted to know whether these differences are significant, 
what type of statistical test I should use, when I have no access to 
underlaying data?

Is it possible to do any statistical test on  such data?

Thank you in advance
