Lavender or light purple is the color typically associated with the tube top for collecting blood samples for potassium testing.
An ethanol level is typically drawn in a gray-top tube containing potassium oxalate and sodium fluoride as preservatives.
A potassium test is used to detect abnormal concentrations of potassium, including high potassium (hyperkalemia) and low potassium (hypokalemia). It is often used as part of an electrolyte panel or basic metabolic panel for a routine physical. So the test in done in a SSP, serum separator tube, with glass/silica particles for enhanced coagulation. The tube stopper top can be gold or red tiger.
The blood for IGF-1 is typically drawn in a plain red-top tube.
TSH (Thyroid Stimulating Hormone) is typically drawn in a lavender/purple-top tube, which contains the anticoagulant EDTA. It is important to check with the specific laboratory or facility to confirm the correct tube color for this test.
Blood for a folate test is typically drawn in a lavender-top tube, which contains the anticoagulant EDTA. The lavender-top tube is used for collecting whole blood specimens for hematology testing.

red top
It could be either red top (to clot it) or Grey top (sodium fluoride or potassium oxalate added) which prevents RBC's from metabolising the glucose in the blood. There is also another one to separate the serum but I forgot the color. It might be "tiger top" or speckled.

RBCs are typically drawn in a purple or lavender-top tube, which contains the anticoagulant EDTA. This type of tube is used for hematology studies and to prevent clotting of the blood sample.
The tube used for a comprehensive metabolic panel (CMP) is typically color-coded as either red, gold, or tiger top.
The tube used for drawing blood for testosterone testing is typically a red-top tube.
A lavender-top (EDTA) tube is typically used for drawing blood samples for hemoglobin electrophoresis testing.
A complete metabolic panel is typically collected in a green or tiger top tube, which contains a gel separator and lithium heparin as an anticoagulant.
