Not exactly. "Color revolutions" happened in those countries after elections and newly formed government asked the Soviets in. Like in Georgia. Populations came later to build infrastructure, to live and to work. Just like Americans to America.
Semantic argument...brief history lesson is in order.
Spoiler :
On September 24, 1939 warships of the Soviet Navy appeared off Estonian ports and Soviet bombers began a threatening patrol over Tallinn and the nearby countryside. Moscow demanded that Estonia allow the USSR to establish military bases and station 25,000 troops on Estonian soil for the duration of the European war. The government of Estonia accepted the ultimatum signing the corresponding agreement on September 28. 1939.
On June 16, the Soviet Union invaded Estonia and presented an ultimatum, demanding the replacement of the Estonian government and free access for Soviet troops. The Red Army emerged from the military bases in Estonia and, aided by an additional 90,000 Soviet troops, took over the country, occupying the territories of Republic of Estonia, and organizing and supporting communist protests all over the country.
On June 17, Estonia accepted the ultimatum. The Estonian government decided according to the Kellogg-Briand Pact not to defend themselves; given the overwhelming Soviet force both on the borders and inside the country, the order was given not to resist, to avoid bloodshed and open war.
On June 21, 1940, the Soviet occupation of the Republic of Estonia was complete. The Flag of Estonia was replaced with a Red flag on Pikk Hermann tower.
On June 21 the President Konstantin Päts (deported to Ufa on July 30 and later arrested) formed a new government under Prime Minister Johannes Vares.
On July 14-15 the rigged, extraordinary single-party parliamentary election were held where all but pro-Communist candidates were outlawed. People were forced to vote under the threat of prosecution, and those who didn't were later arrested on charges of treason and executed. Tribunals were set up to punish "traitors to the people." those who had fallen short of the "political duty" of voting Estonia into the USSR. The communist "Union of the Estonian Working People" "won" an absolute majority of seats. On July 21 the parliament (Riigivolikogu) proclaimed the formation of the Estonian SSR, and, despite the promises given before the election, petitioned to join the Soviet Union on July 22. In response the Estonian SSR was formally incorporated into the Soviet Union (USSR) on August 6, 1940, and nominally became the 16th constituent republic of the USSR.

This is the Estonian government which unfortunately accepted June 17 ultimatum.
Out of 13, 6 died in Soviet prison camps.
5 were executed in Soviet prisons.
1 died fighting Soviet paratroopers.
1 did not return into Estonia from Geneva and thus escaped.
So yeah, not really an occupation. We asked to join.
