This is an example of what I mentioned about Davos plant in regards to unstable colors.
EDIT: Links added http://www.orchidsonline.com.au/node/7443 and http://www.orchidsonline.com.au/node/7427
The 2005 flower shows a more intense yellow on the petals. On the sepals the yellow has a orange tint coming from C. Orange Nugget.
The 2008 flower shows a fainted yellow on the sepals more characteristic to C. Mari's Song. On the sepals the yellow turned in to a cream color.
The plants hybrid formula: Rlc. Haw Yuan Moon x Rlc. Hawaiian Satisfaction

Unstable colors
Unstable colors also occurs in Sarcochilus and some Cymbidium clones.
Phenotypic Polymorphism
Hi Horst, and micogab,
Very interesting, Horst! And this phenomena happened in exactly the same plant, not on another plant(s) obtaining from the same hybridization culture? Or, from the same mericlone culture?
I was used to think that in the same hybrid clones, there are variations to shape, color, structure [Phenotypic Polymorphism?], among different off-springs. But, this is so exciting to learn!
Translating other-wise , the genetic materials are there, but, depending on habitat conditions (temperature, humidity, pH, light intensity, light-length,..), different phenotypic expressions will seasonally result?

Mature....
This is also could be due to maturity i supposed....and i believe that the colour will get more intense as this plant get more mature....

dowiana hybrids
I agree with Phu Vo. I will only add that this is one of the results when when we have C dowiana in the background.C dowiana some times has color variation even on the same flower stem.

Exactly the same plant.
It happens on some of the plants from the same hybridization culture. Other plants from the same hybridization culture have non or only normal small changes from one year to the other.
I do not have experience with mericlone culture.
