If you search on the IWM site
https://www.iwm.org.uk/collections/search dial in separately "272 squadron" and "252 squadron" check "photographs" and "second world war" you will come up with a number of colour photos in the first 20 or 30 hits.
The photos attributed to 272 Sqn seem to show a mixture of Desert Scheme and Temperate Sea Scheme. The photos attributed to 252 Sqn show all TSS. There is a particularly good photo of Beaufighter 'X' of 252 Sqn IWM reference TR 816 which will come up if you search on the ref no.
In b&w photos the TSS shows virtually no tonal contrast between the two upper surface colours the Desert Scheme usually shows quite a high contrast.
